An excerpt from Michael Wolff’s new book, “Fire and Fury: Inside the Trump White House,” claims that President Donald Trump did not know who a key Republican politician was as recently as the day after his election win — a claim that is easily proven to be a lie.

During a meeting with former Fox News head Roger Ailes at Trump Tower the day after the election, Ailes told Trump that he needed someone who could enforce structure in the White House, The Hill reported.

“You need a son of a b*tch as your chief of staff,” Ailes purportedly told Trump. “And you need a son of a bitch who knows Washington. You’ll want to be your own son of a b*tch, but you don’t know Washington.”

Ailes told Trump that he should pick former Republican House Speaker John Boehner.

Wolff claims that Trump responded by asking, "Who's that?"

The notion that Trump did not know who Boehner was is obviously false, as evidenced by tweets from Trump dated years before he ran for president.

Trump's son, Donald Trump Jr., fired back at the accusations, tweeting: "More lies, go back and look, Boehner and #potus spent time together well before the election. Just another pathetic attempt to smear @realDonaldTrump #fakenews."
