U.S. Food and Drug Administration’s (FDA) Commissioner Dr Scott Gottlieb filed his resignation, CNN reported.

"It's is hard for me to write this note to share with you the news that I'll be leaving my job as the Commissioner of Food and Drugs in the next month. There's perhaps nothing that could pull me away from this role other than the challenge of being apart from my family for these past two years and missing my wife and three young children," says the letter, which the FDA tweeted.
According to the report, an administration official said the move has been in the works for several months. Gottlieb has been commuting weekly to Washington from his home in Connecticut and is leaving to spend more time with his family, the official said.
Gottlieb was previously the agency's deputy commissioner for medical and scientific affairs. Appointed by President Donald Trump, he was sworn in as the 23rd commissioner on 11 May 2017. Gottlieb tweeted that he is "grateful for the opportunity to help lead this wonderful agency." President Trump also tweeted about Gottlieb's planned resignation, saying he's done “an absolutely terrific job."
During his tenure as Commissioner, Gottlieb received praise and criticism for his attitude to tobacco and vapour products.
