The Trump administration has pulled CNN reporter Jim Acosta's press credentials after a heated exchange with Trump during a press conference on Wednesday.
She called Acosta's behavior "absolutely unacceptable". It is also completely disrespectful to the reporter's colleagues not to allow them an opportunity to ask a question", she said on "Trish Regan Primetime.
Trump and Acosta have long have a contentious relationship as the CNN reporter often asks the president questions that seemed created to illicit a reaction from him.
Mr Acosta questioned Mr Trump's reference to the caravan as an invasion, and Mr Trump defended the term.
Ms. Hostin gave an example that if she was holding a coffee cup, and then someone struck the cup, that would constitute battery because the cup "is an extension of me".
'CNN should be ashamed of itself having you work for them.
"It was done in retaliation for his challenging questions at today's press conference", CNN communications said in a statement posted to Twitter.
The end result: The White House chose to revoke Acosta's press clearance. Trump repeatedly said "That's enough".
The video Sanders tweeted had been slowed down to show the incident in greater detail, but it did not invent or make up the part where Acosta's arm comes into contact with the intern's.
Acosta tweeted that Sanders' statement that he put his hands on the aide was "a lie". "History will not be kind to you", CNN Matt's Dornic, vice president of communications and digital partnerships, wrote on Twitter Thursday. He threw out a hasty question about the Russian Federation investigation, but President Trump spoke over him.
"A free press is vital to democracy, and we stand behind Jim Acosta and his fellow journalists everywhere".
In response, Acosta said, "This is a lie".
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.
The dramatic White House expulsion of Attorney General Jeff Sessions may be getting all the attention, but there was another one that some consider just as important: the banning of journalist Jim Acosta. Trump's critics have called the deployment a political stunt.
The incident is the latest in a series of clashes between the president and mainstream media outlets, following a spate of comments from Trump calling unfavorable coverage "fake news" and threatening to revoke credentials at some organisations.
While many reporters joined in defending Acosta, several others were quick to point out that they felt he acted inappropriately, "embarrassing the profession".
