James Comey ABC Interview Preview

Comey — whom Trump fired in May 2017 — sat down with George Stephanopoulos for a 20/20 special scheduled to air Sunday at 10pm EST.

In the 30-second promo, Stephanopoulos asks Comey several questions he has not answered since being dismissed from the FBI.

“How strange is it for you to sit here and compare the president to a mob boss?” Stephanopoulos asks the conservative-leaning former FBI chief.

Comey’s new book, A Higher Loyalty: Truth, Lies, and Leadership, is set to be released on Tuesday. He will likely go on a big media tour to promote the novel, and Sunday’s ABC scoop is likely the first stop.

The 57-year-old former FBI director will comment on the charges that have engulfed Trump pertaining to special counsel Robert Mueller’s probe on Russia interference in the 2016 election, as well as other scandals that have surrounded the president.

CNN reported that Jake Tapper will interview Comey on April 19 and that Anderson Cooper will host a town hall with Comey on April 25.

Late Tuesday, House Intelligence Committee Chairman Devin Nunes threatened to “impeach” FBI Director Christopher Wray and Deputy Attorney General Rod Rosenstein if they did not hand over the document that in 2016 ignited the bureau’s investigation of Trump campaign officials’ communications with Russians, per Politico.

“We’re not going to just hold in contempt, we will have a plan to hold in contempt and impeach,” Nunes stated on Fox News.
