President Donald Trump on Saturday ripped into Fox News over planned interviews with former FBI Director James Comey and House Intelligence Chairman Adam Schiff.

Comey and Schiff, who are frequently the targets of Trump's ire, are set to be interviewed by Chris Wallace on "Fox News Sunday."

Trump went after Fox News on Twitter, accusing the network of trying to be "politically correct" with the interviews.

The president then suggested that only pro-Trump shows on Fox News do well, adding that the "rest are nothing."

President Donald Trump attacked Fox News on Saturday night over impending interviews with former FBI Director James Comey and House Intelligence Committee Chairman Rep. Adam Schiff.

In a tweet, Trump accused Fox News of trying to be "politically correct" with the interviews and mocked the network over the fact the Democratic National Committee (DNC) barred it from hosting any 2020 primary debates. The DNC's decision was linked to concerns over the close relationship between Fox News and the president.

Trump on Saturday tweeted: "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!"

In a subsequent tweet, Trump took a jab at Shepard Smith, who recently left Fox News. On a channel with a reputation for pushing a conservative or right-wing narrative, Smith was among the few anchors or hosts who offered critical coverage of the Trump administration.

Trump said: "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?"

Though the president has routinely praised Fox News' opinion hosts for their pro-Trump coverage, he's increasingly gone after the channel's news anchors in recent months — particularly as the impeachment inquiry into his Ukraine dealings escalated.

Comey and Schiff, two of Trump's top targets on social media, will both go on Fox News on Sunday

Comey and Schiff, who have frequently been targeted by Trump on social media, are both set to be interviewed by Chris Wallace on "Fox News Sunday."

The former FBI director, who recently accused "Fox & Friends" of canceling an interview with him, will discuss the Department of Justice inspector general's (IG) report on the origins of the FBI's Russia investigation. The IG report concluded that the Russia investigation was justified and not motivated by political bias, but also found "serious performance failures."

In one of the most controversial moves of his presidency, Trump fired Comey in May 2017 as he was leading the FBI's probe into Russian election interference.

The Russia investigation, which looked into whether there was coordination between the Trump campaign and Moscow, was taken over by special counsel Robert Mueller after Comey was ousted. The investigation ultimately found that Trump's campaign welcomed Russia's interference in the 2016 election, but did not uncover sufficient evidence to bring forward conspiracy charges.

Trump has offered inconsistent reasons for why he fired Comey, but at one point did indicate to NBC's Lester Holt that the Russia investigation factored into the decision.

As chair of the House Intelligence Committee, which has also conducted an investigation into Russian election interference and played a central role in the impeachment inquiry into Trump, Schiff has been repeatedly attacked by Trump on Twitter in recent months. On Fox News on Sunday, Schiff is set to discuss the case for impeaching Trump.

The House Judiciary Committee approved two articles of impeachment against Trump on Friday, and he's expected to be impeached in a full House vote next week. The process will then move to a trial in the Senate, which is expected to begin early next year.
