Journalists, lawmakers, and free press advocates are condemning the Senate’s proposed rules for reporters as President Donald Trump’s impeachment trial gets underway—restrictions which critics say will limit in “unprecedented” ways the media’s ability to cover the proceedings.

As Capitol Hill journalists learned this week of the proposed rules, many took to social media to express outrage.

The rules, proposed by the Sergeant-at-Arms and the Senate Rules Committee, stipulate that reporters would be confined to a single small pen on the second floor of the Senate during Trump’s trial. During normal Senate business—and even major events—journalists have traditionally been permitted to approach senators in Capitol Hill hallways and outside the Senate chamber.

Restricting correspondents to a single area will significantly reduce their access to lawmakers during the historic proceedings, reporters said.

Journalists may also be subjected to additional security screening and their movement around the Capitol may be restricted.

“Every other occasion, including SOTUs, we have been able to balance the equities of lawmakers and media without metal detectors or reporter pens,” tweeted Mike DeBonis, a congressional reporter for the Washington Post. “Completely unclear why this should be any different.”

The Standing Committee of Correspondents, which represents and advocates for journalists on Capitol Hill, reportedly suggested several less restrictive rules to the Sergeant-at-Arms and Sen. Roy Blunt (R-Mo.), chairman of the Rules Committee—but Sarah D. Wire, who leads the Standing Committee, said the proposals were flatly rejected.

“Capitol Hill is one of the most accessible places in Washington, but the proposed restrictions exceed those put in place during the State of the Union, Inauguration Day, or even during the Clinton impeachment trial 20 years ago,” reads the letter.
