Out on the campaign trail and behind the scenes, here's a list of people advising and supporting Bush, compiled by The Washington Post and subject to change as we learn more:
FAMILY AND FRIENDS:
Columba Bush: The candidate’s wife; they’ve been married for 41 years. The couple first met in her home town of Leon, Mexico, when he visited on a high school exchange trip. After marriage, they lived in Venezuela, where he worked as a bank executive, and the family moved two years later to Miami. They speak Spanish to one another and their lives have been immersed in Hispanic culture.
On the campaign trail, Bush frequently mentions the two distinct periods in his life: “B.C. and A.C.: Before Columba and After Columba.”
"I love her dearly, and she has given me a purpose in my life that makes me kind of a grinder, if you will," he once said.
George P. Bush: The eldest of Bush’s children and the oldest member of the family’s next generation. He has two young sons with his wife, Amanda. Bush did a tour in Afghanistan with the Navy Reserve and now serves as Texas Land Commissioner, easily winning election last year. He will travel to Nevada this week to campaign on his father’s behalf and is expected to focus especially on building Hispanic and younger-voter support.
Noelle Bush: Bush’s middle child and only daughter, who he has described as "the joy of my life." She has shunned the spotlight and isn’t expected to play an active role with the campaign. She lives in Orlando and frequently visits her parents in Miami.
Jeb Bush Jr.: Bush’s youngest child is also expected to be the most active. He is his father’s former business partner, lives in Miami and has two young children with his wife, Sandra, who is of Iraqi and Jordanian descent and grew up in Canada. “Jebbie,” as he’s nicknamed, has already headlined several smaller-dollar fundraisers for his father’s super PAC.
George H.W. Bush: The 41st president of the United States. Jeb Bush frequently tells voters that his father is “the greatest man alive.”
Barbara Bush: The former first lady, who suggested in recent years that the country is “Bushed out” but now fully supports her son’s campaign. Proudly outspoken, she said in a recent NBC interview, "I’ve promised that during this next campaign season, I will not talk."
George W. Bush: The 43rd president is Jeb Bush’s older brother and widely seen as one of his biggest political liabilities. The former president has also said he plans to stay out of the limelight during the coming campaign season.
Marvin, Neil and Doro: Jeb Bush’s younger siblings, who are active political figures. Marvin is usually the foil when Jeb jokes about his political family: “A lot of people, they know my dad, they know my brother – and I’m not talking about Marvin,” he once told a Nevada crowd.
Josefina Gallo Esquivel: Jeb Bush's mother-in-law. He has invoked her story in discussions about federally-funded medical research by revealing that she has dementia. Esquivel lives under the care of her daughters in Miami.
John and Lucila Schmitz: If not for them, Jeb and Columba Bush probably would never have met. When Jeb first met Columba in Mexico, she was in a car with John and Lucila, who were dating at the time. The couple lives in Miami near the Bushes and Lucila and Columba's mother (see above).
Jorge Arrizurieta, Al Cardenas and Ana Navarro: They're among Bush's biggest backers and frequently called upon by reporters to illustrate his Miami roots, explain his political appeal or defend his viability. Arrizurieta first met Jeb Bush in the 1980s, held various roles during his governorship and is one of his top donors. Cardenas is a Miami-based super-lobbyist and his children went to school with Bush's. Navarro is a CNN commentator, veteran of Sen. John McCain's 2008 presidential campaign and her boyfriend, Gene Prescott, owns the famed Biltmore Hotel in Coral Gables.
TOP CAMPAIGN AIDES:
Sally Bradshaw: Senior campaign adviser. Next to his family, she’s the most trusted person in his orbit. Bradshaw served as one of Bush’s chiefs of staff when he was Florida governor and has spent most of the past year preparing her former boss to run for president. Her biggest asset? She has Bush's total confidence and vice versa. She lives in Tallahassee on her family’s chicken farm, but will be working from campaign headquarters in Miami.
Danny Diaz: Campaign manager. A Washington native and one-time plumber, he earned the big job last week in a surprise shakeup. At 39, he's a veteran operative who quickly earned the trust of Bush, who recently labeled his new manager "a grinder" -- high praise from the hard-charging governor. Diaz co-founded FP1 Strategies (which stands for "50 percent plus one") with Jon Downs, who will serve as head of Bush's media team (see below). He previously worked for the Republican National Committee, the National Republican Congressional Committee and the presidential campaigns of McCain and Mitt Romney.
David Kochel: Chief strategist. Initially expected to serve as campaign manager, he will focus first on building support in the first four primary states: Iowa, New Hampshire, Nevada and South Carolina. He was one of Bush’s first and boldest staff hires and helped signal the seriousness of the former governor's ambitions. An Iowa native, he’s advised several GOP candidates for years and helped Romney place a close second in the 2012 GOP caucus.
Trent Wisecup: Director of strategy. During the 2012 cycle, he was strategist to the NRCC. He's also worked for former California governor Arnold Schwarzenegger, Sen. Lamar Alexander (R-Tenn.), Bush and Romney. Most recently, he worked for FP1 Strategies.
Justin Muzinch: Policy director. He's one of several Wall Street veterans poised to join Bush's team. Muzinich was most recently a vice president of Muzinich & Co., an international investment firm in New York. He's also been with Morgan Stanley and EMS Capital. Close with Glenn Hubbard, another occasional Bush adviser, Muzinich has advocated for revamping the U.S. Federal Reserve and U.S. foreign aid and has advocated for a new trade deal with Europe.
Scott Jennings: A Kentucky-based consultant who helped reelect Senate Majority Leader Mitch McConnell (R-Ky.) last year. He will advise the campaign on political matters. He ran Romney’s 2012 operations in Ohio.
Heather Larrison: Finance director. It’s her job to woo donors, keep them happy and raise as much money as possible for Bush’s campaign. Her team has an ambitious goal of raising at least $5 million by June 30, in order to show a strong start when campaign finance filings are released July 15. She's been a finance aide for some of the most successful fundraisers in the GOP, including George W. Bush and Sen. Rob Portman (Ohio). She also had stints at the Republican Governors Association and National Republican Senatorial Committee.
Ann Herberger: A Miami-based GOP fundraiser, she runs the Woods Herberger Group, which has focused mostly on raising political money for the Bush family. Herberger has also served as a consultant for the RNC, RGA, NRSC and NRCC.
Jon Downs: Head of media and advertising. He’s Diaz's business partner and worked on George W. Bush’s 2000 campaign, helped run several other state races and worked as a congressional liaison in the Bush Justice Department.
Megan Sowards: General counsel. She held a similar post with the NRSC and was deputy general counsel for Romney's 2012 campaign.
Brenda Gianiny and David Hill: Head of research and polling teams. She served as pollster for George W. Bush’s White House and on his 2004 reelection campaign. He has worked for several top GOP candidates and on behalf of more than 100 state ballot measures, including work that led to six amendments to Florida’s constitution.
Alex Lundry: He’ll be in charge of data analytics. He’s a corporate and political consultant who worked on Romney’s 2012 campaign.
Karen Unger: Head of voter engagement. A seasoned Florida political hand, she served as one of Bush’s deputy chiefs of staff and director of external affairs and appointments. She also ran his 2002 reelection campaign and has managed other Florida political campaigns. Among Unger's early tasks is keeping in touch with Bush’s 650-member alumni network of former staffers.
Annie Kelly: Iowa state director. She's most recently a former FP1 employee. During the 2014 cycle, she was a regional political director for NRCC, helping the GOP win five of the seven most competitive House races. In 2012, she managed the super competitive reelection of campaign of now-former Rep. Tom Latham (R-Iowa) in the Des Moines area.
Rich Killion: New Hampshire state director. He's a longtime Granite State political operative who's managed two statewide campaigns in the state and helped all incumbent GOP state senators win reelection last year.
Brett Doster and Jim Dyke: They're running Bush's operations. Doster is a Tallahassee-based consultant who has known and worked with Bush since his failed 1994 gubernatorial campaign. Dyke has longer ties to George W. Bush -- he was RNC communications director during the former president's 2004 reelection and a press secretary to former commerce secretary Donald Evans, one of the former president's closest friends.
Scott Schied and Ryan Erwin: Bush's Nevada state director and a senior adviser for Nevada. Schied most recently helped Rep. Crescent Hardy (R-Nev.) score a surprise win last year. Erwin worked for Romney's 2008 and 2012 campaigns, once led the Nevada GOP and had stints with Republican Party operations in California and Ohio.
Tim Miller: Campaign communications director. He most recently served as co-founder and executive director of America Rising, a super PAC that has spent millions of dollars digging into the histories of Democrats, especially Hillary Rodham Clinton. As if an encyclopedic knowledge of Clinton wasn't enough, Miller also worked last year on Wisconsin Republican Gov. Scott Walker's reelection campaign, giving him a unique understanding of one of Bush's biggest GOP rivals. He previously worked for McCain's 2008 campaign and Jon Huntsman's 2012 GOP presidential campaign.
Kristy Campbell: National press secretary. One of Bush's longest-serving aides and most frequent traveling companions, she served in his gubernatorial press office and later for his nonprofit education foundation. She was also a member of Romney's 2012 communications team. When reporters have questions about Bush's personal or professional past, Campbell usually gets the first call.
Michael Steel: Adviser for policy and communications. Most recently served as a spokesman for House Speaker John A. Boehner (R-Ohio) and previously as on-the-plane press secretary for Paul Ryan's 2012 vice presidential campaign. A North Carolina native, he worked for the state GOP during Thom Tillis's successful Senate against Democrat Kay Hagan last year.
Emily Benavides: Hispanic communications director – a unique role among top-tier GOP presidential campaigns. It’s her job to keep in touch with reporters for Spanish-language newspapers and television reporters working for Univision, Telemundo and their affiliates. She previously worked for Michigan Gov. Rick Snyder.
Allie Brandenburger: A deputy press secretary, who previously worked for Rep. Jeff Denham (R-Calif.), Romney's 2012 campaign and the RNC.
Matt Gorman: Head of rapid response. He was deputy rapid response director for Romney's 2012 campaign.
Jose Mallea: Head of Latino engagement. A notable hire for Bush, because Mallea was manager of Sen. Marco Rubio's 2010 campaign. But he first made a name as an aide in George W. Bush's administration, holding several jobs, including special assistant to White House Chief of Staff Andrew Card.
Jordan Sekulow: Liaison to the evangelical community. An evangelical Christian attorney, he was executive director of American Center for Law & Justice, a conservative organization founded by televangelist Pat Robertson. Bush is Roman Catholic and eager to build support among conservative Christian Republicans, especially in Iowa and South Carolina.
James A. Baker III, George P. Shultz, Paul D. Wolfowitz, Michael Hayden, Stephen J. Hadley et al: They're part of a 21-member foreign policy advisory team Bush dramatically unveiled in February. The team includes a mix of moderates and neoconservatives who served during the presidencies of George H.W. Bush and George W. Bush. The group mostly consults Jeb Bush from afar.
Josh Venable: A policy aide, he’s been part of Bush’s traveling team, briefing him on the road and keeping tabs on what needs to be followed up on after events. Previously, he's the RNC's former deputy finance director and worked for Bush’s nonprofit education foundation.
Coleman LaPointe: Bush’s first “body guy,” or traveling aide who’s responsible for holding his coat, his phone, snapping “selfies” with supporters, etc. He came with a gold-plated recommendation, having worked as a summer aide to the Bush family at their compound in Kennebunkport, Maine.
Raul Henriquez: Hired recently as another Bush “body guy,” he’ll alternate with LaPointe on the road. He’s a Miami native and former aide to House Speaker John A. Boehner (R-Ohio).

Mike Murphy: Head of the PAC. A top adviser to Bush's 1998 and 2002 gubernatorial campaigns, he most famously worked on McCain’s 2000 presidential campaign.
