On Friday, President Trump shut down CNN White House correspondent and provocateur Jim Acosta during a press conference with British Prime Minister Theresa May, as Trump repeatedly hammered CNN and opted to only answer questions from "real" news networks.

"Mr. President, since you attacked CNN, can I ask you a question?" Acosta asked Trump.

Trump had criticized NBC News reporter Hallie Jackson earlier in the interview, saying that NBC was "possibly worse than CNN."

Trump tried calling on Fox News reporter John Roberts but Acosta would not stop his usual attention-seeking antics.

"Can I ask you a question?" Acosta persisted.

"No, no," Trump replied.

"CNN is fake news," Trump continued. "I don't take questions from CNN. CNN is fake news! I don't take questions from CNN. John Roberts of Fox. Let's go to a real network."

Acosta protested: "Well, we're a real network too, sir."
