Ronny Jackson, the former White House Medical Unit boss turned Republican congressman, is under investigation by the House Ethics Committee.
In a statement, Ethics Committee Chairman Ted Deutch and Ranking Member Jackie Walorski said the panel had taken up a matter referred to it in December of last year, and would announce a “course of action” by 23 May. They did not say what Mr Jackson had been accused of.
Mr Jackson, a Navy veteran who retired at the rank of Rear Admiral, served as chief White House physician during the presidencies of Barack Obama and Donald Trump, but rose to prominence during the latter’s term due to his outrageous statements about Mr Trump’s health, including a session in the White House briefing room during which he claimed Mr Trump had “great genes” and could live to 200 years of age despite being clinically obese.
