U.S. President Donald Trump has launched a fresh broadside at his former ally and now-nemesis Steve Bannon, accusing him of crying and begging for his job after he was fired from his position as White House Chief Strategist.

There were also choice words for Michael Wolff, author of the explosive new book Fire and Fury: Inside the Trump White House, who was branded a “total loser” in Trump’s tweet late Friday night.

Trump said Wolff fabricated stories to sell his book, using “Sloppy Steve Bannon” along the way.

Trump attempted to stop the book from being released, but the book officially released Friday at 9 a.m. ET and is soaring atop Amazon’s Best Sellers list.

Wolff has maintained that he has records and notes of interviews he conducted for the book, and said he spent three hours with Trump himself.

Earlier Friday, Trump heaped praise on a major Republican donor family from distancing themselves from Bannon.

Friday’s tweets came two days after Trump publicly broke with Bannon after he was quoted in Wolff’s book slamming the president’s son Donald Trump Jr. and son-in-law Jared Kushner for what he said was a “treasonous” meeting with Russians.
