Donald Trump called for courts to test NBC and “Saturday Night Live” in a fiery tweet on Sunday that followed the final airing of the sketch show until the New Year.

“SNL” wrapped up a year of political humor directed at the Trump administration with a parody of the Christmas movie “It’s a Wonderful Life,” in which it posited a world wherein Donald Trump, played by Alec Baldwin, was never elected president of the United States.

The sketch, which featured returning guest stars Ben Stiller as Michael Cohen, Robert De Niro as Robert Mueller and Matt Damon as Brett Kavanaugh, showed Trump being led through a Christmas party in a world where Hillary Clinton became president. As each person from his administration approaches, Trump learns that him not being president worked out for the benefit of everyone. For example, the sketch suggested that he and Melania got a divorce and remarried others, Kavanaugh never made it onto the Supreme Court and Mueller was able to spend more time with his kids instead of having to “investigate some idiot for treason.”

Trump responded to the sketch on Sunday morning by jabbing both the sketch show and NBC.

Trump tweeted: “A REAL scandal is the one-sided coverage, hour by hour, of networks like NBC & Democrat spin machines like Saturday Night Live. It is all nothing less than unfair news coverage and Dem commercials. Should be tested in courts, can’t be legal? Only defame & belittle! Collusion?”

Trump previously commented on the content of “SNL” following the season premiere in which Kanye West donned a “Make America Great Again” hat and gave a lengthy speech at the close of the show.

“Like many, I don’t watch Saturday Night Live (even though I past hosted it) – no longer funny, no talent or charm. It is just a political ad for the Dems. Word is that Kanye West, who put on a MAGA hat after the show (despite being told “no”), was great. He’s leading the charge!” Trump tweeted at the time.

As Variety notes, Trump has also come after NBC in the past for what he perceives to be unfair coverage, even calling for the FCC to take action against the network’s broadcast license.
