It was during this exchange the female staff member attempted to take the microphone from Mr Acosta. Trump has called the move an "invasion", although the group is nowhere near the United States border. Trump shouted him down.
The video shows most of the incident at normal speed, but just as Acosta is gesturing with his left arm and the intern reaches under to grab the mic, it speeds up. "This conduct is absolutely unacceptable", she said.
Many in the media industry were furious with Ms Sanders for sharing the video, including one of Mr Acosta's colleagues. "We stand by our statement", Sanders said in a statement. "We do have to stick together, but Jim Acosta makes it awfully hard to have journalistic solidarity in something like this".
The White House suspended Acosta's press credentials after the press conference, limiting his access to the White House grounds.
The move to punish Acosta by removing his access to the White House is believed to be unprecedented. "We will not tolerate the inappropriate behavior clearly documented in this video", Sanders tweeted to accompany the allegedly doctored video. The video is clear.
President Trump dismissed his characterization of the caravan as a "difference of opinion", adding, "I want them to come into the country, but they have to come in legally".
"If that takes a walkout, a boycott or turning off the cameras when the president is at the podium, they should do it", Aaron said.
Acosta called out the misleading ad released by the Republican Party and said: "They're hundreds of miles away, though. That is not an invasion". But the president used rhetoric and his bully pulpit to try to make a point.
"I tell you what, CNN should be ashamed of itself having you working for them", the President said, shaking a finger at Acosta.
'That's enough, Put down the mike, ' Trump told him.
What do you think of this exchange?
"The edited video looks authentic: Acosta appeared to swiftly chop down on the arm of an aide as he held onto a microphone while questioning President Trump. You should not be working for CNN".
"I'm not a fan of yours either". "You run CNN and if you did it well, your ratings would be much better".
President Trump insulted Mr Acosta after the reporter challenged his recent assertions about a migrant caravan heading to the USA from Central America.
