NEW YORK: CNN, MS NOW and Politico are due in Washington federal court on Thursday as they urge a judge to extend their protection against being banned from the White House on president Donald Trump’s order.

Trump’s revocation of the outlets’ access for publishing what he said was “FAKE NEWS” was the latest escalation of his pressure campaign against media coverage he dislikes.

He said he might ban other outlets but was unsure it would hold up in court.

US district judge Timothy Kelly temporarily blocked the ban on Sept 24, finding it likely violated the outlets’ right to fair treatment under the Constitution's Fifth Amendment.
