US President Donald Trump has offered lukewarm support to his pick to lead the Veterans Affairs department, Ronny Jackson, amid claims of impropriety.
Mr Trump said at a news conference that he will “stand behind” the embattled White House doctor, but added: “If I was him, I wouldn’t do it”.
Dr Jackson is facing allegations he oversaw a toxic work environment in the White House Medical Unit.
On Tuesday a Senate committee abruptly cancelled his confirmation hearing.
CBS News and other US media outlets have reported that the doctor has been accused of “excessive drinking on the job”, “improperly dispensing” medications and fostering a “hostile work environment” during his tenure at the White House.
