During his first press conference since the election, Donald Trump got into a back-and-forth exchange with CNN reporter Jim Acosta over the news organization's coverage of the unverified report -- first posted on BuzzFeed -- claiming Trump's deep ties with Russia.

While answering a question relating to his earlier tweet asking "Are we living in Nazi Germany," Trump specifically called out BuzzFeed as a "failing pile of garbage" and CNN for building up the story after BuzzFeed first released it.

When Trump finished his response, Acosta could be overheard trying to ask a question.

"Since you're attacking us can you give us a question? Since you are attacking our news organization can you give us a chance?" Acosta said.

"Not you, your organization is terrible," Trump responded, telling Acosta to be quiet. "She's asking a question, don't be rude."

Acosta however kept trying to ask his question, until Trump ended the exchange by declaring CNN to be "fake news."

"No, I'm not going to give you a question. You are fake news!" he said.

"Mr. President-elect that's not appropriate," Acosta said before allowing the next reporter to ask her question.

Acosta appeared on CNN to discuss the incident.
