CNN sued the administration Tuesday after the White House stripped correspondent Jim Acosta of his press credentials last week following a heated exchange between the reporter and Trump at a post-election press conference.
Wallace said Fox News meant to file a formal brief in support of CNN with the court ahead of an afternoon hearing.
The White House revoked Acosta's credentials last week in an escalation of the Republican president's attacks on the news media, which he has dubbed the "enemy of the people".
The lawsuit, which was filed against the Trump Administration and several of his aides on Tuesday, alleges the suspension violates Acosta's First and Fifth Amendment rights.
A dispute over the press credentials of CNN's chief White House correspondent has escalated into a potentially significant legal showdown over journalists' rights, as the cable network and the Trump administration prepared for a hearing in federal court today. In 1977, a lower court ruled against the Secret Service for pulling the pass of a reporter without establishing and following standards for doing that. This was not the first time this reporter has inappropriately refused to yield to other reporters. "And he has seized it with the communication channel, with the tweeting and the rallies and the press conferences", the longtime reporter told CNN's Jake Tapper.
Burt Neuborne, a New York University professor, was on "CNN Tonight" explaining the situation between the president and Acosta when Lemon revealed his grand theory that the White House staged the incident.
"He's got a loud voice", Trump said, adding, "You have to treat the White House of the office of the president with great respect".
"The President and White House possess the same broad discretion to regulate access to the White House for journalists (and other members of the public) that they possess to select which journalists receive interviews, or which journalists they acknowledge at press conferences", said the brief filed ahead of a court hearing in the case. Acosta kept talking and holding a White House handheld microphone given to speakers as they ask their questions.
Wallace said while Fox News doesn't condone the "growing antagonistic tone by both the president and the press at recent media avails", it supports "access and open exchanges for the American people".
"We do not believe that revoking White House press credentials is an appropriate remedy for a disagreement the White House may have with a particular reporter", CBS News' statement said.

Trump's attorneys argued it would be "extraordinary" for the court to decide to "directly police access to the secure White House complex where the president lives and works, as well as to dictate who the President must invite to press events". The "hard pass" allows the bearer to enter White House areas as an employee might, undergoing a less onerous security check, and without an invitation or request for entrance.
