Steve Bannon reportedly called Paul Ryan a 'limp-d--- motherf-----'

White House chief strategist Steve Bannon once called House Speaker Paul Ryan a "limp-d--- motherf----- who was born in a petri dish at the Heritage Foundation," according to a new book on Bannon's relationship with the president.

The book "Devil's Bargain: Steve Bannon, Donald Trump, and the Storming of the Presidency," written by Bloomberg Businessweek correspondent Joshua Green, was released this week and includes some colorful anecdotes about the top White House adviser.

Bannon's crude insult was reportedly made last July when a sudden fear took hold of him that Ryan would try to wrest the nomination from Donald Trump during the Republican National Convention.

Ryan had previously said he would not make such an attempt, insisting, "I do not want, nor will I accept the nomination for our party."

But despite this assurance, Bannon reportedly spiraled "into a panic of his own" at the prospect. He spit out the insult while he was in Breitbart's Washington, DC newsroom, according to Green's book.

Bannon's mention of the Heritage Foundation was meant as an additional slight against Ryan — Bannon reportedly believes the conservative think tank caters to the "globalist donor class."

Bannon doled out a number of creative insults during the campaign, according to Green's book, including calling then-Fox News host Megyn Kelly "pure evil" following the infamous Republican primary debate in which she grilled Trump on his past behavior towards women.
