White House prepares for possible Jackson withdrawal

New allegations of improper behavior against Rear Adm. Ronny Jackson, the White House physician, came as a surprise in the West Wing when they were published by Senate Democrats Wednesday afternoon and have left the President and his aides more uncertain about whether Jackson's nomination can move forward, three White House officials said.

While the White House was preparing for the possibility Jackson could withdraw, it was not clear Wednesday evening whether Jackson was leaning toward dropping out or pressing forward.

The President and his aides are now openly discussing the possibility that Jackson could pull his nomination, the officials said, and aides late Wednesday afternoon began preparing for a possible withdrawal -- though White House officials said the decision remains Jackson's.

Trump's thinking on Jackson's nomination has been rapidly evolving. Earlier on Wednesday, he raised the prospect of going into the briefing room today to stick up for Jackson, simply to say he is a good guy and has his support.

But several senior administration officials, including White House press secretary Sarah Sanders, advised him against doing so.

The fresh allegations appeared to change even the President's thinking, who wondered aloud on Wednesday afternoon whether Jackson should step aside now "before things get worse," an official said. Trump was also astonished that few have publicly come to Jackson's defense leading the President to believe Jackson's fate is more perilous than it seemed.

Asked Wednesday evening about CNN's reporting, White House spokesman Raj Shah said aides were "of course" preparing for the possibility that Jackson could withdraw his nomination.

"This is, as the President said, Dr. Jackson's decision," Shah said on "Erin Burnett Outfront." "We stand behind him 100% depending on what he decides to do. We think he'll make a great secretary of Veterans Affairs, but this is a nasty process right now."

Emerging from the White House press secretary's office earlier on Wednesday, Jackson said he would continue to fight on.

"We're still moving ahead as planned," Jackson said, adding denials of several of the fresh allegations, including that he had wrecked a government car after drinking.

But his comments belied the increased skepticism about the fate of his nomination inside the White House. One official conceded the raft of new allegations makes it harder for the White House to provide a defense.

Senate Democrats on Wednesday afternoon released a two-page document summarizing allegations 23 current and former colleagues of Jackson have made against him behind closed doors. Lawmakers have not yet substantiated the claims and are investigating them further, but they included allegations that he was "abusive" to colleagues, loosely handled prescription pain killers and was periodically intoxicated.

Speaking on Capitol Hill Wednesday evening, White House Legislative Affairs Director Marc Short acknowledged the claims of misconduct that surfaced hours earlier caught the administration off guard.

"It appears these allegations were brought to senators and so in some cases all of us are in the dark as to the allegations themselves," said Short, who added he planned to meet with Jackson at the White House on Wednesday evening.
