Describing Acosta's behaviour as "disgusting and outrageous", the White House Press Secretary Sarah Sanders, in a statement on Wednesday said, "As a result of today's incident, the White House is suspending the hard pass of the reporter involved until further notice".
The end result: The White House made a decision to revoke Acosta's press clearance. During the intern's final attempt, as she tried to pull the microphone away, Acosta's hand appeared to briefly brush her arm.
The sparring started after Acosta asked Trump about the caravan of migrants heading from Latin America to the southern US border.
When Acosta tried to follow up with a question about Russia, Trump replied: "CNN should be ashamed of itself having you working for them". That's enough. That's enough.
Trump demanded the CNN reporter "put down the mic".
"Well, when you report fake news - no, when you report fake news, which CNN does a lot - you are the enemy of the people", a fuming Trump said before wandering away from the podium again.
Mr Acosta's press pass was later cancelled amid accusations that he "placed his hands" on the intern.
We urge the White House to reconsider this overreach of power and to reinstate Jim Acosta's credential immediately.
President Trump pointed to his poll numbers among African Americans and then ripped the question as "racist". The way you treat Sarah Sanders is terrible. That's the moment that Sanders referred to in her tweet explaining why Acosta had been barred. "We will not tolerate the inappropriate behavior clearly documented in this video", she wrote in a tweet.
In a statement announcing the disciplinary measure Wednesday evening, Sanders said, "President Trump believes in a free press and expects and welcomes tough questions of him and his administration".
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. The president turned away, trying to go on to another reporter, but Acosta refused to give up his microphone.
She continued, saying that reporters are "not supposed to be the story" and adding that she was "frustrated" watching the interaction between Acosta and Trump.
Sanders defended her claim by posting a video on Twitter on Wednesday night.
Trump also accused Acosta of treating Press Secretary Sarah Sanders in a way that was "awful".
When the issue came to a head in June 2016, Trump told CNN in an interview that, if elected, he would not revoke credentials.
