Majority Leader Mitch McConnell asked President Donald Trump in one of their first meetings to stop his talk of “draining the swamp,” according to former White House chief strategist Stephen Bannon.

In an interview to air Sunday on CBS News'”60 Minutes,” Bannon decried the lack of support from the Republican establishment for the new president.

“I think Mitch McConnell, and to a degree, [House Speaker] Paul Ryan… do not want Donald Trump’s populist, economic nationalist agenda to be implemented,” he told host Charlie Rose. “It’s very obvious… obvious as night follows day.”

Asked to give an example of how they were “trying to nullify the 2016 election,” Bannon recalled an early meeting at Trump Tower.
