The House and Senate will begin placing new, temporary restrictions on who can access the Capitol and congressional office buildings as lawmakers ramp up efforts to prevent the spread of the coronavirus.

Paul Irving, the House sergeant at arms, and Michael Stenger, the Senate sergeant at arms, said in a joint statement that the restrictions will go into place starting at 5 p.m. on Thursday.

"Access to the Capitol and the House and Senate Office buildings will be limited to members, staff, credentialed press and official business visitors," they said.

As The Hill reported on Wednesday night, Capitol tours are also being temporarily suspended.

"We are taking this temporary action out of concern for the health and safety of congressional employees as well as the public. We appreciate the understanding of those with planned visits interrupted by this necessary, but prudent, decision," they added.

The new restrictions are expected to remain in place until April 1.

Lawmakers had been under growing pressure to take action after Washington, D.C., got its first coronavirus cases and several lawmakers had to self-quarantine after being exposed to an individual with the virus.

In addition to Capitol tours, the White House has also suspended tours and the Pentagon has also canceled tours.

The decision was made before Sen. Maria Cantwell (D-Wash.) announced that a staffer had contracted the virus, the first known case on Capitol Hill.
