Former FBI director James Comey compared President Trump to a mob boss in a new ABC News interview that is set to air this weekend.

Comey, fired by Trump last May, has largely remained quiet about the President and his administration over the past 11 months, but it appears thats about to change.

The interview with ABCs George Stephanopoulos, airing Sunday at 10 p.m. as part of a 20/20 special, is going to shock the president and his team, a source told Axios.

How strange is it for you to sit here and compare the President to a mob boss? Stephanopoulos asks the axed former bureau head in a promo released by the network.

He also asks whether Comey believes the President obstructed justice. Comey does not speak in the clip.

The interview will be followed by appearances on The View, CNN, MSNBC and Fox News in the coming week as Comey promotes his new book, “A Higher Loyalty, which is out on Tuesday.

Comeys dismissal paved the way for the appointment of special counsel Robert Mueller, who is now overseeing the federal investigation into Russian election meddling and probing whether the Trump campaign colluded with the Kremlin to sway the contest in Trumps favor.

The Stephanopoulos sit-down will certainly add more meat to the charges swirling around Trump, Axios added.

Comey spent five hours wih Stephanopoulos, according to Politico.

Comey made waves last year when he spoke candidly in congressional testimony about his interactions with the President and told lawmakers he took detailed notes after each exchange.

Trump has railed against the former FBI boss, accusing him of lying.

Mr. President, the American people will hear my story very soon. And they can judge for themselves who is honorable and who is not, Comey tweeted in March.
