Marc Short on Thursday quit his position as Director of Legislative Affairs in President Donald Trump administration in the United States.
He becomes the latest senior aide to exit the administration.
An economic advisor to Trump will replace Short.
Short has been one of Trump’s longest serving and more visible aides, routinely seen on Capitol Hill as he sought to shepherd legislation through the Senate and House of Representatives.
White House Chief of Staff John Kelly described Short as “an integral part” of the staff, an official who helped the president pass measures to rebuild the military and reform the tax code.
“We will miss his profound expertise, commitment to the taxpayers, and leadership,” Kelly said.
