The White House physician to US presidents Barack Obama and Donald Trump has denied allegations that he drank on the job.
Ronny Jackson, a medical doctor and former US Navy admiral, dismissed findings of misconduct detailed in a Pentagon watchdog report.
"That is not me and what is alleged did not happen," Mr Jackson, now a pro-Trump congressman, said.
He said the report was politically motivated.
The Pentagon report summarised findings from a years-long review launched in 2018 and examines allegations against Mr Jackson from as far back as 2012.
It found that the former White House doctor, who joined the White House medical team under George W Bush in 2006, disparaged colleagues, improperly used sleeping pills and was repeatedly found to have been drinking on duty.
