It was during this exchange the female staff member attempted to take the microphone from Mr Acosta.
White House Press Secretary Sarah Sanders has been accused of sharing a "doctored" video of CNN correspondent Jim Acosta's interaction with a White House intern that resulted in the reporter's press pass being revoked.
Their arms momentarily come together as the woman tries to take the microphone off him.
Acosta said Sanders' account of the incident was "a lie".
Following a lengthy and tense verbal back-and-forth, in which Trump at one point started to stray from his lectern and he called Acosta "a rude, awful person", a female White House intern tried to take the microphone from Acosta.
"(Sanders) provided fraudulent accusations and cited an incident that never happened.
CNN news- Who is Jim Acosta?
Journalists assigned to cover the White House apply for passes that allow them daily access to press areas in the West Wing.
Following the news conference, Ms Sanders said: "President Trump believes in a free press and expects and welcomes tough questions of him and his administration. To be honest. You aren´t the best", he said.
At the conference Trump, when asked if he had "demonized immigrants" during the midterms campaign, replied: "No, I want them to come into the country". That means, come January, the gavels for key congressional committees will pass from Republican legislators to Democrats, who are certain in a target-rich environment to issue subpoenas and hold hearings on matters ranging from alleged collusion between Russian Federation and Trump's 2016 election campaign to questionable spending on travel by members of the president's Cabinet.
While Trump appeared comfortable and relaxed, he grew upset quickly after Acosta was called upon and refused to let other reporters speak after Trump answered his four questions.
"They can play that game, but we can play it better", he said.
He repeated that Acosta was a "very rude person", adding, "the way you treat Sarah Huckabee is awful", referring to his White House press secretary. "You shouldn't treat people that way". "You shouldn't treat people that way". "I've traveled with him and watched him", Alexander said. "He's a diligent reporter who busts his butt like the rest of us".
"I consider it an invasion, you and I have a difference of an opinion", Trump responded.
The "Jersey Girl Embarrassed by Bob Menendez", as Conway has dubbed herself on Twitter, also said that she doesn't think "anybody should have - any young woman, particularly - should have somebody swiping away at them, grabbing the microphone back". "You should not be working for CNN".
Trump has repeatedly called him "fake news", turning him into a symbol of the president's general animus toward the news media.
Albright said videos like this pose an even greater risk of perpetuating misinformation than completely faked news videos, because they contain a grain of truth and will likely be given the assumption of accuracy.
"You know what the word is", President Trump said, concluding a testy exchange at Wednesday's news conference.
"We stand by our decision to revoke this individual's hard pass".
In a later tweet, Sanders said the White House stood by its decision.
President Donald Trump speaks during a news conference in the East Room at the White House in Washington, Nov. 7, 2018.
He turned specifically on reporter Yamiche Alcindor of PBS' NewsHour. "Some people saw that as emboldening white nationalists".
"Such a racist question", Trump complained, adding that he found it "insulting". "What do you say to that?"
