A ruling is expected to come down today in the suit by CNN to get back Jim Acosta’s press pass, which was revoked last week after a heated back-and-forth with President Trump.

One of the big questions is why the White House pulled Acosta’s press pass. CNN has argued that the White House pulled the pass because it was unhappy with Acosta’s coverage and that this amounts to a violation of the First Amendment. The White House initially claimed that Acosta assaulted a White House intern, who was trying to take his microphone, and then changed its reasoning, saying that Acosta was behaving disrespectfully.

Does the president have the right to pick and choose which journalists get a press pass? If so, using what standards? We examine the legal arguments behind the suit.
