Who: Kellyanne Conway, counselor to President Donald Trump.
New role: Last week, U.S. Attorney General Jeff Sessions announced that Trump had asked Conway to become the administration's "opioids czar." She will "coordinate and lead the effort from the White House" to stem the opioid-abuse epidemic, Sessions said. Trump has yet to name a director for the Office of National Drug Control Policy, who typically spearheads White House efforts on drugs.
Background: A lawyer by trade, Conway has no previous experience in addiction medicine or public health. She has been cited by administration officials for assisting in the drafting of a report issued by the President's Commission on Combating Drug Addiction and the Opioid Crisis.
Past positions: Conway previously served as one of Trump's campaign managers, becoming the first woman to run a successful presidential campaign. She has previously worked as a pollster and a Republican political strategist.
