A1: The stories you need to read before your first conference call.

-- ISIS rebels captured Tal Afar, a town on the Iraq-Syria border, on Sunday, sending hundreds of ethnic Turkmen families fleeing into the desert. This weekend, ISIS posted gruesome photos of what it said was a mass execution of Iraqi Army troops. The group tweeted it had executed 1,700 men, while an Iraqi military spokesman said airstrikes on the ISIS-controlled town of Balad had killed 278 rebels. A suicide bombing in Baghdad killed 14 people. (Washington Post)

-- The American Embassy in Baghdad plans to temporarily evacuate a large number of personnel this week and bolster security staff guarding the Green Zone. The embassy has about 5,500 staffers, many of whom are staying in Baghdad; those who are leaving will be flown to Amman, Jordan, or to consulates in Irbil or Basra. (New York Times)

-- Russia said it would cut off gas supplies to Ukraine on Monday after the two countries failed to agree on a price for natural gas. Gazprom said Monday it would require Ukraine to pay for all natural gas in advance; Russia says Ukraine owes $4.5 billion in energy bills. (Washington Post)

-- Vice President Joe Biden is extending his trip to Latin America to convene a high-level meeting of regional officials to discuss a surge of young immigrants streaming across the U.S.-Mexico border. Biden will meet with the presidents of Guatemala and El Salvador and a top official from Honduras on Friday, the White House said in a Sunday conference call. Children are pouring across the border after hearing rumors that anyone in the U.S. by year's end will be eligible to stay here permanently. (Politico)

-- The Senate returns this week to begin the appropriations process. Paul Kane's Take: The committee is supposed to have these last two weeks of June and two weeks of July to move Appropriations bills. Several have already been approved 30-0 or 29-1 in committee, which means Senate Minority Leader Mitch McConnell supports them, at least by proxy. As many as half a dozen Approps bills should make it through the Senate by next month -- unless gridlock over procedures and allowing amendments gums up the system again. If that happens, Senate business is done for the year.

-- In Case You Missed the Friday News Dump: The IRS said Friday it has lost emails sent by Lois Lerner before 2011 because her computer crashed that summer. Technicians said they sent Lerner's computer to the forensic lab used by the IRS's criminal investigations unit, but that lab couldn't recover the emails either. The IRS did find 24,000 emails between 2009 and 2011 on which Lerner had copied other employees. The IRS said it had spent nearly $10 million and used 250 employees to assist congressional investigators. (Associated Press)

-- U.S. officials believe the Haqqani network ultimately agreed to release Sgt. Bowe Bergdahl because one of the five released Taliban detainees was Mohammad Nabi Omari, a low-ranking Taliban official but an associate of the Haqqani network. The CIA paused drone attacks for five months earlier this year that coincided with new efforts to retrieve Bergdahl; now that he's free, the CIA has resumed the drone strikes. (Tribune Co.)

-- Front Pages: WaPo and USA Today lead with embassy evacuations in Baghdad. NYT, LAT, WSJ lead with ISIS's claims of mass execution in Iraq.

Palace Intrigue: Inside the Republican leadership races

-- What we know: Rep. Kevin McCarthy (R-Calif.) is going to be the next House Majority Leader. He's locked up the votes, and his major challengers recognized that last week when they dropped out.

-- Rep. Raul Labrador's (R-Idaho) campaign isn't going anywhere; even some of his close friends have told him they know it's a lost cause. He just didn't lay down any foundation, even though he told friends he was thinking about running (if Jeb Hensarling didn't) as early as last Wednesday, during a meeting of conservative members in Rep. Scott Garrett's (R-N.J.) office.

-- What we don't know: Whether Rep. Steve Scalise (R-La.), the front-runner in the Whip race, has locked up enough votes to guarantee a first-ballot victory. Rep. Pete Roskam (R-Ill.), the current chief deputy whip, promised to pick a deputy from a red state if he wins in a letter to colleagues this weekend. Some members saw that as a Hail Mary. Roskam's biggest drawback is that he's from Illinois in a conference dominated by Southerners, but led by non-Southerners (Ohio, California, Washington, Oregon, Kansas).

-- Will Rep. Marlin Stutzman (R-Ind.) play the spoiler, or the also-ran? He laid almost no groundwork before jumping in the whip's race, and he was only making his first contacts with some members on Sunday night, via text message. He clearly draws votes from Scalise, but whether he will draw enough to force a second ballot is unclear. It helps Stutzman's cause that Rep. Jim Jordan (R-Ohio) is whipping for him.

-- Robert Costa Wants To Know: How much establishment support does Rep. Cathy McMorris Rodgers' (R-Wash.) endorsement of Scalise carry? Will Scalise or Roskam offer Stutzman the chief deputy whip position to win his support on a second ballot? Will Boehner, Cantor or McCarthy put thumbs on the scales, however gently? (They'd do it for Roskam, a close McCarthy ally, if for anyone) Will Tea Party/outside groups get involved and try to rally grassroots support? That doesn't always work out well. (All the more reason to follow @CostaReports)

-- Names to Know: If Roskam wins the whip race, put David Mork, his chief of staff, and Dean Thompson, his deputy chief, on speed dial. Scalise's top aide, Lynnel Ruckert, has been laying a foundation for her boss's eventual run for months. Roskam is seeking second-ballot commitments, and second ballots can be unpredictable: Roy Blunt almost won the House Majority Leader job on the first ballot back in 2006, before John Boehner took a majority on the second ballot.

National Roundup: What's happening outside the Beltway.

-- WH'16: Maryland Gov. Martin O'Malley (D) keynoted the Manchester Democratic Party's annual Flag Day Dinner, where he recited the Star Spangled Banner. (Baltimore Sun)

-- Massachusetts: State Democrats on Saturday voted to endorse Treasurer Steve Grossman (D) for governor, dealing a setback to Attorney General Martha Coakley (D), who leads by a wide margin in public polling. Delegates to the party convention said they were still wary of Coakley after her 2010 loss to Scott Brown in a special Senate election. Coakley, Grossman and former Medicaid chief Donald Berwick (D) will face off in the Sept. 9 primary. (New York Times) Coakley leads Grossman by a 49 percent to 14 percent margin, according to a new Boston Globe poll; she leads businessman Charlie Baker (R) by a 42 percent to 31 percent edge. (Boston Globe)

-- California: State legislators on Sunday passed a $156 billion budget package for the fiscal year beginning July 1. The deal, a compromise with Gov. Jerry Brown (D), begins to pay down a $74 billion shortfall in teacher pension funds and sets aside more than $2 billion in rainy day and reserve funds. One Republican, state Sen. Anthony Cannella, voted with Democrats to give the measure the required two-thirds majority. (Sacramento Bee)

-- Idaho: The state Republican convention adjourned abruptly on Saturday without electing a chairman or adopting a platform after rival factions fought over seating delegates from Boise. Rep. Raul Labrador (R), the chairman of the convention and an ally of the current party chairman, had tried to broker a deal between libertarian and Tea Party forces and more establishment types aligned with Gov. Butch Otter (R) for weeks, though those efforts failed. (Spokane Spokesman Review)

-- Iowa: Delegates loyal to Gov. Terry Branstad (R) wrested control of the state Republican Party's executive board from supporters of Ron and Rand Paul on Saturday. They will install a new chairman in coming weeks. The new leadership could do away with the quadrennial straw poll, which Branstad has said he doesn't like. (Politico) Louisiana Gov. Bobby Jindal (R), Sen. Rand Paul (R-Ky.) and former Sen. Rick Santorum (R-Pa.) addressed Iowa Republicans at their state convention in Des Moines on Saturday. (Reuters)

DC Digest: What's on tap today in DC.

-- President Obama wakes up this morning in Rancho Mirage, Calif., where he spent the weekend with his family. On Sunday, Obama called Spain's King Juan Carlos I, who this week hands power to his son, Crown Prince Felipe. On Tuesday, Obama heads to Pittsburgh to tour a technology firm and New York for two DNC fundraisers.

-- Vice President Biden spent the weekend in Delaware. This morning, Biden departs D.C. for stops in Brazil, Colombia, the Dominican Republic and Guatemala. Biden will watch tonight's U.S.-Ghana World Cup game in Natal before flying to Brasilia to meet with President Dilma Rousseff. Biden stops in Bogota on Wednesday, the Dominican Republic on Thursday and Guatemala on Friday.

-- The House returns to D.C. tomorrow.

-- The Senate holds its first votes at 5:30 p.m. on cloture for three judicial nominations, in Washington State, Illinois and Florida. Confirmation votes would follow Tuesday morning.

TV Time Out: Our exclusive look at who's advertising, and where.

-- Battle for the Senate: Spending on TV time in key Senate battleground states since the beginning of January has topped $100 million. Democrats and Republicans have spent the most, more than $25 million, in North Carolina, and more than $15 million each in Alaska, Colorado, Michigan and Arkansas. All told, Republicans and their outside allies have spent $58.6 million since January 1, while Democrats have spent $57.7 million. (Washington Post)

-- Mississippi: Sen. Thad Cochran (R) is locking up cable time over the next week-plus before the June 24 runoff. Late last week, Cochran's campaign bought $120,000 in cable ads across the seven markets that cover his state, set to run through the 24th. We haven't seen any broadcast ads come through yet, but you can bet they're on the way.

-- North Carolina: EMILY's List will kick off a $3 million independent expenditure campaign on behalf of Sen. Kay Hagan (D) today with their first TV ad hitting state House Speaker Thom Tillis (R) on education funding. The group says it will spend that money on mail, digital and television ads.

The Buried Lede: The nuggets that deserve the spotlight.

-- "New York State forbids corporations from giving more than $5,000 a year to candidates and political committees. But limited liability companies -- businesses that share attributes of corporations and partnerships -- are allowed to give up to $60,800 to a statewide candidate per election cycle and up to $150,000 a year to candidates and committees overall. What's more, corporations and individuals can set up an unlimited number of LLCs through which to donate, making the caps effectively meaningless."

-- Gov. Andrew Cuomo (D) has pledged to close that loophole. Instead, he's become its biggest beneficiary, accepting $6.2 million from LLCs since he took office three years ago. That's a little under 20 percent of the total amount Cuomo has collected in advance of his re-election bid this fall. (ProPublica)

B1: Business, politics and the business of politics

-- Sources say the NRCC will encourage candidates to reassess their relationship with pollster John McLaughlin after his poll so badly missed the mark in House Majority Leader Eric Cantor's race last week. McLaughlin's clients this year include Georgia Senate candidate Jack Kingston (R), Virginia U.S. House candidate Barbara Comstock (R), and New York state Sen. Lee Zeldin (R), who's running against Rep. Tim Bishop (D). (The Hill) Kingston has released internal polling in advance of his July 22 runoff against businessman David Perdue (R). That's the next -- maybe final -- test of McLaughlin's capabilities.

-- A decade after the Ground-based Midcourse Defense system, which is supposed to intercept U.S.-bound missiles, was declared operational, it cannot be relied on, even in scripted tests. The U.S. has spent more than $40 billion on the missile shield; in sixteen tests, eight have failed. The system has 30 interceptors -- four at Vandenberg Air Force Base in California and 26 at Fort Greely, Alaska -- that could be easily overwhelmed by an attack with multiple missiles, according to Missile Defense Agency projections. (Los Angeles Times)

-- Markets are down in early hours trading after making small gains on Friday. Most world markets are trading lower today. (CNN)

C1: The long reads you'll need to check out before tonight's cocktail party.

-- White House officials met nearly every day for weeks after former NSA contractor Edward Snowden fled to Hong Kong and Moscow, searching for ways to apprehend him. Led by homeland security advisor Lisa Monaco, the meetings ended the same way: With everyone promising to make more appeals to their Russian counterparts, and praying that Snowden would screw up. Attorney General Eric Holder says the U.S. knows "exactly where Mr. Snowden is," but other U.S. officials say they don't know where he lives or the extent the Russian security service, the FSB, plays in his daily life. (Washington Post)

-- D.C. city councilman Marion Barry (D) says Bill Clinton asked him for advice on getting through difficult personal situations during the Monica Lewinsky scandal. In a new memoir to be released Tuesday, Barry describes himself as constantly under assault from white critics, and he goes into explicit detail about his arrest at the Vista Hotel for drug use. Barry plans a big public rollout, including an interview with Oprah Winfrey later this week. (Washington Post)

C4: The comics page, fun things to read when you're bored at work

-- Fans celebrating the L.A. Kings' Stanley Cup win Friday night outside the Staples Center managed to knock an L.A.P.D. drone out of the sky with what looks like a shoe. Riot police had sent the drone in to keep an eye on overly enthusiastic Kings fans. Maybe they'll fly it a little higher the next time a Los Angeles team wins a championship. (Business Insider with the must-see gif.)

-- Hillary Clinton signed books at an Arlington Costco this weekend. One of the shoppers who picked up a copy: Sonia Sotomayor. Politico's Maggie Haberman snapped a photo.

Attn Matt Drudge: Things conservatives will get outraged by today.

-- Campbell, Wis., police chief Tim Keleman has been suspended after admitting to investigators that he harassed a Tea Party activist by signing him up for accounts on online dating and porn sites. The activist, Greg Luce, had sued the town over a ban on signs and banners on a pedestrian bridge. (Milwaukee Journal Sentinel)

Attn HuffPo: What outrages liberals today

-- No single company spent more lobbying the Kentucky legislature this year than Altria Group, the parent company of Philip Morris USA and U.S. Smokeless Tobacco. The company spent $156,000 pestering legislators this year, and it got just about everything it wanted, including industry-backed regulations on electronic cigarettes. (Louisville Courier-Journal) Altria has given more than $900,000 to federal candidates this cycle, four and a half times the amount the next largest tobacco contributor, Reynolds, has donated.
