Last week, the White House revoked the press pass of CNN's chief White House correspondent, Jim Acosta, and denied him access to the building.
CNN responded by filing suit in federal court against the president.
Acosta's First and Fifth Amendment rights had been violated, said CNN. The demand: Acosta's press pass must be returned immediately and his White House press privileges restored.
"If left unchallenged," CNN warned, "the actions of the White House would create a dangerous chilling effect for any journalist who covers our elected officials." A dozen news organizations, including The New York Times and The Washington Post, are filing amicus briefs on CNN's behalf.
On Thursday, the Trump administration raised the stakes.
Justice Department lawyer James Burnham declared in court: "If the president wants to exclude all reporters from the White House grounds, he clearly has the authority to do that."
After all, whose house is it if not the "President's House," the home of Donald Trump as long as he serves in the office to which he was elected by the American people?
The West Wing contains the Oval Office and the offices of senior staff. As for the West Wing briefing room, it was built by President Richard Nixon in 1969, when White House passes were regarded as privileges.
When did they become press rights or press entitlements?
Is Trump obligated to provide access to whomever CNN chooses to represent the network in the West Wing, even if the individual assigned routinely baits the press secretary and bashes the president?
Whence comes this obligation on the president?
White House aides can be fired, forced to surrender their passes and be escorted out of the building.
Whence comes the immunity of White House correspondents?
The First Amendment guarantees CNN reporters and anchors the right to say what they wish about Trump. It does not entitle Acosta to a front-row seat in the White House briefing room or the right to grill the president at East Room press conferences.
