Via Roll Call, some disturbing news about impeachment coverage:

The Senate sergeant-at-arms and Capitol Police are launching an unprecedented crackdown on the Capitol press corps for the impeachment trial of President Donald Trump, following a standoff between the Capitol’s chief security officials, Senate Rules Chairman Roy Blunt and the standing committees of correspondents.

Capitol Police Chief Steven A. Sund and Senate Sergeant-at-Arms Michael C. Stenger will enact a plan that intends to protect senators and the chamber, but it also suggests that credentialed reporters and photographers whom senators interact with on a daily basis are considered a threat.

Additional security screening and limited movement within the Capitol for reporters are two issues that are drawing criticism from Capitol Hill media.

The Standing Committee of Correspondents, which represents journalists credentialed in the daily press galleries in the House and Senate, has come out forcefully against the planned restrictions that it says rejected every suggestion made by the correspondents “without an explanation of how the restrictions contribute to safety rather than simply limit coverage of the trial.”
