Rear Adm. Ronny Jackson, President Donald Trump's nominee for secretary of veterans affairs, has come under intense scrutiny over allegations of workplace misconduct.

CNN on Tuesday night detailed a 2015 incident in which sources said Jackson became intoxicated and banged on the hotel-room door of a female employee.

One source told CNN that Jackson had caused such a scene that the Secret Service intervened out of concern that he might wake up President Barack Obama.

New allegations emerged Tuesday night about the conduct of the White House physician, Rear Adm. Ronny Jackson, including a claim that he once banged on the hotel-room door of a female employee while intoxicated.

CNN cited four people familiar with the allegation as saying the doctor caused a ruckus by banging on the door of a woman's hotel room during an overseas trip in 2015. One source told CNN the noise was loud enough that the Secret Service intervened out of concern that he would wake President Barack Obama.

A former staffer said the "middle of the night" incident made the woman uncomfortable and was "definitely inappropriate," CNN reported.

That story adds to a flurry of recent allegations against Jackson, who is scheduled to go before the Senate Committee on Veterans' Affairs on Wednesday. The hearing was postponed Monday amid multiple allegations stemming from his time as the White House physician.

Among those allegations are claims of excessive drinking at work, creating a hostile work environment, and improperly dispensing medication, according to a CBS News report published Monday night.

Jackson had already been under fire from some lawmakers who expressed doubt over his ability to lead the nation's second-largest agency. After serving as the White House physician under George W. Bush, Obama, and now Trump, Jackson was thrust into the spotlight after performing Trump's first physical as president, delivering a glowing report on Trump's health.

Before this week, it was questions over Jackson's lack of management experience that most surrounded his nomination, which came shortly after the ouster of David Shulkin as VA secretary.

Earlier Tuesday, Trump appeared to express some doubt over his nominee. "I know there's an experience problem, because lack of experience," Trump said during a press conference.

"I don't want to put a man through a process like this," Trump continued, adding: "The fact is I wouldn't do it. I wouldn't do it. What does he need it for? To be abused by a bunch of politicians?"

Jackson on Tuesday morning did not deny the allegations in a video posted by MSNBC, saying only that he was "looking forward to the hearing so we can sit down and I can explain everything to everyone," but CNN later quoted Republican Sen. Jerry Moran of Kansas as saying Jackson did deny the allegations, including drinking on the job.
