Some have tried to tie the attack on journalists to Trump’s fiery rhetoric against the media, but the attacker appeared to be motivated by his own personal vendetta against what he saw as unfair treatment by the news outlet.

As Trump began to leave the room, Acosta yelled, “Mr. President will you stop calling us the enemy of the people?!” several times.

“I tried to ask the president if he would stop calling us the enemy of the people,” Acosta tweeted later. “He did not respond.”
