A visibly angry Trump called reporter Jim Acosta a "rude, bad person", after the CNN White House correspondent refused the president's orders to sit down and yield the microphone during the conference one day after the USA midterm election.
That's when the staffer attempted to take Acosta's microphone away, and Acosta said "pardon me, ma'am", while he continued to try to ask his question.
The CNN journalist at the White House on Wednesday engaged in a tense tug-of-war with Trump, who after answering several of his questions, said "That's enough".
In another video of the encounter tweeted by Sarah Burris, an editor at the left-leaning political blog Raw Story, the footage has been slowed down and annotated to show the four times the White House intern touches Acosta while trying to take the microphone.
To make matters worse, Sarah Sanders lied - and circulated a misleadingly edited video to back herself up - when she claimed later that Acosta was being punished for "placing his hands on a young woman".
In a later tweet, Mr Acosta said Ms Sanders' assertion he placed his hands on the woman was "a lie".More news: Chinese Workers Made To Drink Urine For Failing To Finish Tasks
Acosta was repeatedly trying to ask Trump about his referral to a migrant caravan headed to the USA from Central America as an "invasion".
Acosta has been one of the most outspoken reporters covering the administration since Trump took office.
"That's enough, that's enough", the president said, before telling Mr Acosta to sit down and to put down his microphone. They way you treat Sarah Huckabee is disgusting and the way you treat other people are awful.
Trump said that if Democrats brought forth strong legislation on issues important to them such as the environment, infrastructure, and healthcare, then it was possible some Senate Republicans would help pass the legislation and Trump would then sign it. "You and I have a difference of opinion", he said. You are a rude awful person. "While President Trump has made it clear he does not respect a free press, he has a sworn obligation to protect it", CNN added.
White House staffers decide whether journalists are eligible, though the Secret Service determines whether their applications are approved.
"I understand", Alexander said, attempting to ask a question.
Even Ben Shapiro, a notoriously conservative commentator, defended the CNN journalist, writing back to Sanders that her account was "not what happened".More news: Fossil Sport watch announced with Wear 3100 and ultra lightweight body
Acosta said he learned that his access was withdrawn from a text message on his phone.
Waving his finger, Mr Trump berated him.
They are not only risky, the are disturbingly un-American.
"It is also completely disrespectful to the reporter's colleagues not to allow them an opportunity to ask a question", she said.
Trump has repeatedly called him "fake news", turning him into a symbol of the president's general animus toward the news media.
