White House won't back down as attorney predicts how Trump's latest press tussle will play out in court

An attorney at a nonprofit that defends the First Amendment doesn't think President Donald Trump will come out on top in a legal battle with three media outlets he banned from the White House.

But after announcing on Friday his ban of CNN, MS NOW and Politico — and the resulting lawsuit against him — the White House told Fox News Digital that Trump isn't backing down.

"I think the Trump administration will not fare well in court because its action here is blatantly unconstitutional," predicted Aaron Terr, the director of public advocacy at the Philadelphia-based Foundation for Individual Rights and Expression (FIRE).

Trump took to TRUTH Social on Friday to announce that employees with the three major media outlets will be banned from White House grounds over "reporting FAKE NEWS.

He said they "shouldn't be able to constantly write or report FICTION and LIES when they're covering the President of the United States." DISNEY SUES FCC OVER ‘RETALIATORY CAMPAIGN AGAINST ABC,’ SEEKS TO BLOCK EARLY RENEWAL PROCEEDINGS Terr says that what media outlets report is not at issue.

"There's settled precedent that when the White House opens its doors to the press, which it has done, the First Amendment walks in too," Terr said.

"So that means the administration can't ban reporters from the White House grounds just because it doesn't like their point of view or thinks their coverage is too negative or critical, and the president in his statements has been crystal clear that this was the exact reason that he banned CNN, MSN, and ...

Politico from the entire White House grounds." Reporters and cameramen with the outlets removed their gear and set up on Pennsylvania Ave. over the weekend and this week continued to film live hits from across the street rather than from their usual spots on White House grounds.

In response to Terr's assessment, the White House remained defiant about the ban.

CNN FIRES BACK AT TRUMP WHITE HOUSE OVER ATTACKS ON REPORTER, CALLS THEM 'BENEATH THE OFFICE' Monday morning, the three news outlets filed a lawsuit against Trump seeking an injunction that would halt the president's ban temporarily, and asking the court to immediately order the restoration of the media members' White House credentials.

CNN was scheduled for White House television pool coverage on Monday.

Fox News Media, ABC News, CBS News and NBC News, the other press pool networks, announced in a joint statement that they would not take CNN's place.

"The public has a vital interest in receiving accurate, independent information about its government.

No administration should restrict a news organization because it objects to its reporting," the pool members said in a joint statement.
