President Trump slammed Fox News for planning interviews with former FBI Director James Comey and House Intelligence Committee Chairman Adam Schiff.

"Hard to believe that @FoxNews will be interviewing sleazebag & totally discredited former FBI Director James Comey, & also corrupt politician Adam “Shifty” Schiff. Fox is trying sooo hard to be politically correct, and yet they were totally shut out from the failed Dem debates!" Trump said on Saturday night.

He later compared the network to "Commiecast" MSNBC and CNN, saying, "They'll all die together as other outlets take their place."

"Only pro Trump Fox shows do well," he said. "Rest are nothing."

Both Commiecast MSNBC & Fake News CNN are watching their Ratings TANK. Fredo on CNN is dying. Don’t know why @FoxNews wants to be more like them? They’ll all die together as other outlets take their place. Only pro Trump Fox shows do well. Rest are nothing. How’s Shep doing? — Donald J. Trump (@realDonaldTrump) December 15, 2019

The cable news network said they would exclusively interview James Comey on Fox News Sunday with host Chris Wallace this weekend. Schiff will also be featured on the Sunday morning show, according to Fox's website.

Comey is expected to defend himself against accusations that he and other FBI officials opened an investigation into alleged collusion between the Trump campaign and Russia during the 2016 presidential election out of anti-Trump bias. Schiff will likely speak on the impeachment proceedings against the president.

"So it was all lies," Comey said in a Monday tweet. "No treason. No spying on the campaign. No tapping Trumps wires. It was just good people trying to protect America."

Comey's scheduled appearance on the network comes after he accused Fox & Friends of booking and canceling an interview with him earlier this week following the release of the Department of Justice inspector general's report, which found that bias among FBI officials did not lead to the opening of the 2016 Russia investigation.

Fox News later denied that Comey had ever been booked for the interview.
