This is reported by Fox News.

After the opening speech of the president and representatives of the administration, the press was asked to leave the hall.

Journalists started shouting questions.

“For one reason I don’t like to do this: you never cover the substance of the meeting,” Biden said.

As noted, a few lines were shouted out by Fox News correspondent Peter Doucy.

Biden, in response to Dusi's cries, noted that the journalist's words were "a valuable observation."

According to Fox News, then the American leader continued his speech and, "almost without moving his lips," made an insulting phrase to the correspondent. 

Earlier, Joe Biden called the journalist's question about the way to build relationships with his Russian counterpart Vladimir Putin stupid.
