WASHINGTON (AP) -- President Donald Trump fired Veterans Affairs Secretary David Shulkin on Wednesday and nominated White House doctor Ronny Jackson to replace him in the wake of a bruising ethics scandal and a mounting rebellion within the agency.
A Navy rear admiral, Jackson is a surprise choice to succeed Shulkin, a former Obama administration official and the first non-veteran ever to head the VA. Trump had been considering replacements for Shulkin for weeks, but had not been known to be considering Jackson for the role.
In a statement, Trump praised Jackson as "highly trained and qualified." It was a decision that signaled Trump chose to go with someone he knows and trusts, rather than the candidate with the longest resume, to run a massive agency facing huge bureaucratic challenges.
Jackson has served since 2013 as the physician to the president, one of the people in closest proximity to Trump day in and day out.
His profile rose after he conducted a sweeping press conference about the president's medical exam in January in which he impressed Trump with his camera-ready demeanor and deft navigation of reporters' questions as he delivered a rosy depiction of the president's health, according to a person familiar with the president's thinking but not authorized to discuss private conversations.
Jackson eagerly embraced the idea of moving to the VA, according to a White House official who spoke on condition of anonymity to discuss personnel matters. Ironically, it was Shulkin who had recommended Jackson for an undersecretary position at the agency in fall. Jackson was vetted during that time on his policy positions and other issues, the official said.
The promotion of Jackson marks the latest Trump hire to be driven at least as much by personal familiarity with the president as by his vision for the role.
Brigadier General Dr. Richard Tubb, who trained Jackson, said in a letter read at Jackson's briefing that the doctor had been attached like "Velcro" to Trump since Inauguration Day.
"On any given day," he wrote,"the 'physician's office,' as it is known, is generally the first and last to see the President."
A White House official said Shulkin was informed of his dismissal by Chief of Staff John Kelly before the president announced the move on Twitter on Wednesday afternoon.
Trump had considered several others for the post, including conservative "Fox & Friends" contributor Pete Hegseth. The White House was hopeful Jackson will have a smoother confirmation process because he was chosen for his current position during former President Barack Obama's administration.
But a major veterans' organization expressed concern over Shulkin's dismissal and Trump's intention to nominate Jackson, whom they worried lacked experience to run the huge department.
"We are disappointed and already quite concerned about this nominee," said Joe Chenelly, the national executive director of AMVETS. "The administration needs to be ready to prove that he's qualified to run such a massive agency, a $200 billion bureaucracy."
Rep. Phil Roe, chairman of the House Veterans Affairs Committee, said he believed Shulkin did a "fantastic job" and didn't think he should have been dismissed, but "at the end of the day, cabinet secretaries serve at the pleasure of the president."
"I respect President Trump's decision, support the president's agenda and remain willing to work with anyone committed to doing the right thing on behalf of our nation's veterans," Roe said. "I am in the process of reaching out to Dr. Jackson and I look forward to building a strong relationship with him also."
Shulkin is the second Cabinet secretary to depart over controversies involving expensive travel, following former Health and Human Services Secretary Tom Price's resignation last September. Trump said in a statement he is "grateful" for Shulkin's service.
Shulkin had continued to insist he had the full confidence of the White House amid continuing investigations into his travel and leadership of the department.
He had agreed to reimburse the government more than $4,000 after the VA's internal watchdog concluded last month that he had improperly accepted Wimbledon tennis tickets and that his then-chief of staff had doctored emails to justify his wife traveling to Europe with him at taxpayer expense. Shulkin also blamed internal drama at the agency on a half-dozen or so rebellious political appointees, insisting he had White House backing to fire them.
But the continuing VA infighting and a fresh raft of watchdog reports documenting leadership failures and spending waste -- as well as fresh allegations that Shulkin had used a member of his security detail to run personal errands -- proved too much of a distraction.
It was the latest in a series of departures of top administration officials, including Secretary of State Rex Tillerson, who was fired by Trump earlier this month, and national security adviser H.R. McMaster, whose departure was announced last week.
The VA change comes as Trump is trying to expand the Veterans Choice program, fulfilling a campaign promise that major veterans' groups worry could be an unwanted step toward privatizing VA health care. His plan remains in limbo in Congress after lawmakers declined last week to include it in a spending bill.
Having pushed through legislation in Trump's first year making it easier to fire bad VA employees and speed disability appeals, Shulkin leaves behind a department in disarray. Several projects remain unfinished, including a multibillion-dollar overhaul of electronic medical records aimed at speeding up wait times for veterans seeking medical care as well as expanded mental health treatment for veterans at higher risk of suicide.
Trump selected Robert Wilkie, undersecretary of defense for personnel and readiness, to serve as the acting head of the VA.
The VA is government's second-largest department, responsible for 9 million military veterans in more than 1,700 government-run health facilities. The selection of Wilkie bypasses VA Deputy Secretary Tom Bowman, who has come under criticism for being too moderate to push Trump's agenda of fixing veterans' care.
During the presidential campaign, Trump repeatedly pledged to fix the VA, which was still reeling after a 2014 scandal at its Phoenix medical center, where veterans waited months for care even as VA employees created secret waiting lists to cover up delays. Criticizing the department as "the most corrupt," Trump said he would bring accountability and expand access to private doctors, promising to triple the number of veterans "seeing the doctor of their choice."
Currently, more than 30 percent of VA appointments are made in the private sector.
