Craig Aaron of the activist group Free Press called Trump's actions "a direct and risky attack on the public's rights to hold their leaders accountable" and called for "a unified stand" by the press corps. He was trying to reenter the White House grounds for a live shot on "Anderson Cooper 360" when he was stopped by Secret Service officers.
After the exchange, CNN, through its public relations department's Twitter feed, said Trump's attacks on the press have gone too far.
"As you know, Mr. President, the caravan is not an invasion", Acosta said. "I never thought that in this country I wouldn't be able to cover the president of the United States just for asking a question", he said.
Waving his finger, Trump berated him.
The President blasted: "I'm not concerned about anything with the Russian Federation investigation because it's a hoax".
When Acosta tried to ask further questions, Trump became angry, demanding that the reporter sit down and give up the microphone.
"Honestly, I think you should let me run the country". "You have a president that does not live in a fact-based world a lot of the time and his tone was so aggressive, but you also have people in the press core that are constantly aching to make the headlines and to get those soundbites".
"I think we have crossed a new line, because the reason for taking away Acosta's credentials is a lie", said Dan Kennedy, a Northeastern University journalism professor.
US Attorney General Jeff Sessions resigns
The Department of Justice shared a letter from Sessions showing that he " submitted his resignation " at the request of Trump. Trump announced in a tweet that Sessions' chief of staff Matt Whitaker would become the new acting attorney general.
CNN said in a statement that Sanders "lied" on Wednesday night. Acosta has been addressing tough questions to both the president and his press secretary for almost two years. She said that "on the campaign trail, you called yourself a nationalist".
The WHCA called on the White House to "immediately reverse this weak and misguided action".
Journalists assigned to cover the White House apply for passes that allow them daily access to press areas in the West Wing.
"I worked with Jim @Acosta at CNN". He doesn't like that there are some white nationalists who are supporting the president. Trump interrupted her, calling it a racist question. "What do you say to that?" As I told the officer, I don't blame him.
'You are a very rude person, ' Trump told him.
Alcindor moved on to a different topic.
Trump also shut down American Urban Radio Networks' April Ryan. "I've never seen a president do anything like that".
Buzzfeed reported there was no evidence the video shared by Watson was deliberately sped up, but that by changing format into a lower-quality GIF, it turned "the question of whether it was "doctored" into a semantic debate".
