"The irony of this White House video involving Jim Acosta is that if it is found to be doctored, it will show the administration to be doing what it accuses the news media of doing - engaging in fake information", said Aly Colon, a professor in journalism ethics at Washington & Lee University.
Acosta learned his pass had been revoked as he attempted to enter White House grounds for a live broadcast on Wednesday evening.
Reporters don't get routine access to the Prime Minister's Office, but media credentials to access Parliament Hill are managed by the National Press Gallery, not the PMO.
On Friday, CNN called Trump's statement an "unprecedented threat" that "poses a serious challenge to the White House press corps and the association that represents them". When you're in the White House, this is a very sacred place to be.
Wednesday's performance was never about journalism, and the first clue to that is how few questions Acosta actually asks. "You shouldn't be working for CNN", he said.
But at the White House, he has often outsourced the job of booting employees to his chief of staff - and then announced the departures via Twitter. But I watch you a lot.
"I came in here as a nice person wanting to answer questions, and I had people jumping out of their seats screaming questions at me", said Trump, who talked for almost 90 minutes despite the run-ins with reporters.
"I think Jim Acosta is a very unprofessional man-he does this with everybody". Matt Dornic, a CNN executive, tweeted at Sanders that her behavior was "absolutely shameful".More news: Thousands of Residents in Vicinity of Woosley Fire Without Power

Shapiro says that when Acosta's hand touches the intern's arm as she reaches for his microphone, the action speeds up in the apparently altered video to accentuate his movement. She's the White House press secretary!
Trump also took a shot at CNN journalist, April Ryan, calling her "nasty" and a "loser".
Other social media users are sharing one of Mr Trump's tweets from 2013 where he criticises the "intimidation of its reporters". "This is a very special place", Trump said.
She says that she'd been asking about voter suppression, a far more serious problem than voter fraud.
"There are embarrassingly few black and hispanic reporters in the WH press corps and four have been personally insulted by the President this week", he wrote.
See what I did there? There are those saying this was definitely doctored (the AP) and those saying it definitely was not (Vice) and several people in between saying this doesn't appear to be doctored but does have a couple extra frames along with framerate, compression, and other issues that made it look different than the original C-Span clip.
Trump said he hadn't made a decision when asked by a reporter how long Acosta would remain in the "penalty box".
