Speaking Wednesday at his first press conference since being elected president, Trump lambasted CNN for reporting Tuesday night that he was briefed by intelligence officials on an unverified dossier alleging that the Russians had gathered compromising information on him.

Though CNN reported that the memos had not been confirmed, Trump dismissed CNN reporter Jim Acosta’s attempts to ask a question at the press conference, calling the news network “terrible.”

"Don't be rude,” Trump told Acosta as he attempted to ask a question. “No, I'm not going to give you a question. You are fake news."

Trump has frequently turned his ire on the press, calling reporters “dishonest” and criticizing specific news organizations that critically report on him as “failing.” He has also suggested that as president, he would “open up” libel laws to make it easier to sue news organizations.
