John Boehner is the linchpin to immigration and the debt ceiling. Here’s why.

WHAT YOU MIGHT HAVE MISSED:

Rubio says immigration bill needs changes to pass: Sen. Marco Rubio (R-Fla.) kept up his skepticism about the odds the bipartisan immigration bill he helped craft will win passage. "I can tell you that the bill as it is currently structured isn’t going to pass the House," Rubio said after a meeting with the Republican Study Committee.

Obama to return to Brandenberg Gate: President Obama will return to Berlin later this month for a speech at the Brandenberg Gate, where he delivered an address as a candidate in 2008 that drew more than 200,000 people. Obama's speech will be June 19.

Martinez for president? Doesn't sound like it. New Mexico Gov. Susana Martinez (R) sure doesn't sound interested in running for president in 2016. "As the first Hispanic female governor in the country, I have a lot of little girls who come up to me, and they know who I am. They know that I'm the governor. They get big-eyed and they call me by my first name, and I've got to set an example for them and pave a path for them," Martinez told Hotline On Call. "I can't abandon this job and not do it honorably and to the fullest extent possible that benefits them. And so I wouldn't do it because of them." Martinez faces reelection in 2014.

Rice reaction: Sen. John McCain (R-Ariz.) said he does not agree with Obama's decision to tap U.N. Ambassador Susan Rice as his next national security adviser, but will "make every effort to work w/ her on imp’t issues." Sen. Rand Paul (R-Ky.) offered a harsher assessment, saying “I can’t imagine, one, that we would be keeping Ambassador Rice in any significant position, much less promoting her to an important position."

Holt is in: Rep. Rush Holt (D-N.J.) will run for late Sen. Frank Lautenberg's seat. He will join a Democratic field also expected to include Newark Mayor Cory Booker and Rep. Frank Pallone. On the GOP side, former Bogota mayor Steve Lonegan, a conservative candidate, announced that he will run. The filing deadline for the special election is Monday, giving potential candidates little time to decide on the race.

Obama jokes about Flacco, Biden: Obama offered Ravens QB and Super MVP Joe Flacco high praise at a White House ceremony honoring the Super Bowl champs. "I’d say that if you keep on playing like that, you’re going to challenge Biden for the most popular person from Delaware," the president quipped. Flacco is a University of Delaware graduate.

West slams Holder: Former Florida Republican congressman Allen West writes in a new fundraising e-mail for his PAC that Attorney General Eric Holder is more dangerous than al-Qaeda.

GOP in control in Nebraska Senate race: Attorney General Jon Bruning leads a hypothetical Senate Republican primary matchup, but former treasurer Shane Osborn (R) has the best favorability in the field, according to a new poll from GOP pollster Harper Polling. A generic Republican leads a generic Democrat by 20 points. The survey was automated and likely unable to reach 39 percent (according to a 2011 estimate) of Nebraskans who lack cellphones.
