Marty Makary out as head of US Food and Drug Administration

US Food and Drug Administration (FDA) Commissioner Marty Makary is leaving his post, President Donald Trump said on Tuesday.

Makary, in the role for just over a year, had faced criticism both from inside and outside the Trump administration, including for his resistance to authorising flavoured vapes and to tightening restrictions on abortion pills.

"He was having some difficulties," Trump told media at the White House, adding that the role would be filled by a deputy until a permanent replacement is found.
