CNN anchor Anderson Cooper closed his show on Wednesday night by mocking President Trump for his “unusual tic” of speaking in the third person, comparing him to the “Sesame Street” character Elmo.

President Trump spoke to reporters earlier in the day and attacked the Mueller probe as a “witch hunt.”

“We just went through the Mueller witch hunt, where you had, really, 18 angry Democrats that hate President Trump. They hate him with a passion,” Trump said.

Cooper cried foul on numerous fronts.

“Him! He is him! Why is he doing this?” Cooper asked. “Also, grammar aside for a moment, if he says ‘witch hunt’ one more frickin' time, Glinda is gonna float down from Oz and tell Lee Greenwood to hit the yellow brick road because Dorothy has arrived with the Lion, the Tin Man, and the Scarecrow. Of course, the Scarecrow doesn’t have a brain, but even if he did, the third-person-in-chief wouldn’t be worried.”

The CNN anchor then played a clip of Trump boasting about China’s respect of “Donald Trump and for Donald Trump’s very, very large brain” during a 2018 news conference.

“The president of the United States is not supposed to talk like Elmo... Speaking in the third person, it was a habit for President Trump long before he moved to 1600 Sesame Street,” Cooper continued.

He then invoked a 2012 tweet in which Trump congratulated himself for high ratings when he starred on “The Apprentice.”
