Fox News announced on Wednesday that it supports CNN's efforts to restore Jim Acosta's White House credential after the network filed a lawsuit against the Trump administration.

"Fox News supports CNN in its legal effort to regain its White House reporter's press credential. We intend to file an amicus brief with the U.S. District Court. Secret Service passes for working White House journalists should never be weaponized. While we don't condone the growing antagonistic tone by both the president and the press at recent media avails, we do support a free press, access and open exchanges for the American people," Fox News President Jay Wallace said in a statement.

Howard Kurtz, host of Fox News Channel's"MediaBuzz" and author of the new book  "Media Madness: Donald Trump, The Press, And The War Over The Truth," joined Fox News Radio's Marie Harf to give his take on CNN's lawsuit against the Trump administration. 

On news outlets supporting CNN: By revoking his credentials the White House sort of went to death con one and now the reason you have NBC and CBS and ABC and FOX and other news organizations not just backing CNN but actually filing court briefs is that there's a consensus that even though Acosta is not the idle poster boy for freedom of the press they can't sit by while the White House says we're going to banish this reporter. You can not call on him. You can freeze him out, but to take away his credentials so he can't even get in past the gates I think has almost forced many news outlets to side with CNN. (1:10)

On Acosta being denied access by Secret Service in France:  The Secret Service is doing it's job. Interestingly, the Secret Service agent who told Jim Acosta that first day, 'I'm sorry you can't come past the gates,' he was named in the lawsuit too. It wasn't his decision. He's like the cop on the corner.  (5:53)

On the court of public opinion on the White House: I think in the court of public opinion both sides are playing to their base. CNN now has a largely anti-Trump audience, which is cheering it on cheers on Jim Acosta. CNN has made no attempt to reign in Jim Acosta, who likes to debate rather than question the President and it's audience probably loves it.  The President's supporters hate the media, don't like CNN, particularly don't like Jim Acosta and are applauding the fact that he put Acosta in his place.  (7:38)
