CNN anchor Jake Tapper blasted President Donald Trump's lengthy press conference on Thursday afternoon, calling Trump's tirades against the media "wild" and "unhinged."

"It was an airing of grievances. It was Festivus," Tapper said.

Trump took questions from reporters for more than an hour after announcing his new nominee for labor secretary, Alexander Acosta. He used much of the time to rage against negative coverage of his administration, and he complained about specific reports about his campaign's ties to Russia.

While insisting that the coverage was incorrect, Trump also criticized officials who leaked information to the reporters, at one point saying, "The leaks are absolutely real. The news is fake."

Tapper said Trump was "whining" rather than "offering an optimistic, positive view of what he's doing for the country," and he suggested that Americans would not view Trump's remarks favorably.

"If you are a soldier in harm's way right now, if you are a hungry child in Appalachia or the inner city, if you are an unemployed worker in a hollow shell of a steel town, that's not a president who seemed rather focused on your particular needs and wants," Tapper said. "That's a president focused on his bad press."

Tapper continued: "A lot of Americans are going to watch that press conference and think, 'That guy is not focused on me. I don't even know what he's focused on.'"
