The letter reportedly went on to elaborate those rules, including that at presidential press conferences, reporters can only ask a single question and follow-ups will only be permitted "at the discretion of the President or other White House officials," CNN said.
Failure to abide by these rules "may result in suspension of revocation of the journalist's hard pass," the letter states.
Following an incident on November 7 when Acosta pressed US President Donald Trump with repeated follow-up questions and refused to surrender the microphone, the White House pulled his press pass. Trump later called Acosta's behavior distracting and disrespectful. A lawsuit resulted in Judge Timothy Kelly of the District Court for the District of Columbia granting a 14-day injunction on Acosta's pass revocation last Friday. However, the Trump administration immediately indicated its intention to re-revoke that pass once the court order expired.
CNN tweeted Monday afternoon that "the @WhiteHouse fully restored @Acosta's press pass. As a result, our lawsuit is no longer necessary. We look forward to continuing to cover the White House."
