During a segment on Saturday, Acosta mocked Trump and his supporters for pushing claims that Joe Biden did not win the election and that Trump could be back in the White House as early as this summer.

Acosta said of the former president and his loyalist supporters: “The insurrectionist-in-chief is back in the news this week. You remember Donald Trump and his motley crew, or is that motley coup?”

He then played clips of Sidney Powell and former national security adviser Michael Flynn at the recent QAnon conference in Dallas, Texas where they said Trump could “simply be reinstated,” or appeared to support a coup to return him to the White House, respectively.

Flynn would later backtrack on his comments and claimed he had never called for a coup in America, despite video of him appearing to endorse an uprising like the one in Myanmar.

Acosta then accused Trump of “stirring this pot for weeks” and played a clip from the May 10 edition of the Joe Pags Show where the former president appeared to push the claim that Biden did not win the election.

Trump said in the segment: “It’s going to be a very interesting time in our country. You understand what that means, I mean how do you govern when you lost?”

Acosta later called out former Vice President Mike Pence for failing to properly challenge Trump over the riot at the Capitol on January 6.

He said: “Don’t see eye to eye? Agree to disagree, on an insurrection? What makes this so dangerous is that this could happen again.”

Acosta rubbished claims made by MyPillow CEO Mike Lindell that Trump would return to the White House later this summer and added: “There is no mechanism for Trump to get reinstated.

“That is delusional. If Trump really believes he will be back in the White House this August, he should get help. You are not well, sir. You need to get over this.”

He then channeled Jimmy Buffett’s famous tune “Margaritaville”, adding: “Same goes for the GOP.

“It’s as if much of the Republican Party is trapped in a Jimmy Buffett tune. Wasting away in Mar-A-Lagoville. Some people claim there’s an orange man to blame, but I know it’s my own damn fault.”

A representative for Donald Trump told Newsweek: “Mr. Acosta is clearly not taking CNN’s falling ratings very well. It’s quite sad to watch the network’s rapid slide toward irrelevance.”
