One of Donald Trump's advisers says the president-elect is no longer interested in his rallying cry "drain the swamp."

"I'm told he now just disclaims that. He now says it was cute, but he doesn't want to use it anymore," former House Speaker Newt Gingrich said in an interview that aired Wednesday on NPR. Gingrich, a vice chairman of the transition team, also predicted there would be "constant fighting" over Trump's efforts to reduce the influence of lobbyists and Washington insiders.

Trump's aides say he remains committed to his underlying swamp-draining policies, such as banning outgoing Trump transition and administration members from lobbying for five years. Trump also prohibits any lobbyists from joining his transition team or administration unless they de-register.
