Harrisburg, PA (AP) — Pennsylvania is doubling the number of National Guard members it’s sending to help secure Washington after the riot last week at the U.S. Capitol.

Gov. Tom Wolf announced Friday he’s sending about 1,000 more to help with the inauguration of Democrat Joe Biden on Wednesday.

He’s previously deployed about 1,000 to Washington. Wolf has also called up about 450 Guard members to protect the Pennsylvania Capitol in Harrisburg and other possible targets of unrest.

The FBI has warned of the potential for armed Trump supporters to cause trouble at state capitols.

Harrisburg, PA – Governor Tom Wolf announced that approximately 1,000 additional Pennsylvania National Guard (PNG) members have been activated to support the District of Columbia (D.C.) National Guard and D.C. civil authorities in preparation for the upcoming presidential inauguration. This will bring the total number of PNG members supporting operations in Washington, D.C., to approximately 2,000.

“As the number of Guard forces from around the country continues to build in Washington, D.C., Pennsylvania is now sending an additional 1,000 of its Guard members to help ensure the safe and peaceful inauguration of President-elect Joe Biden,” said Gov. Wolf. “By having one of the largest Guards in the nation, the Pennsylvania Guard has the trained resources needed to respond to concurrent missions within our commonwealth, across our nation and overseas. I am thankful for their selfless service, as well as the sacrifices of our service members’ families and their employers, especially during these unprecedented times in our nation’s history.”

Pennsylvania has the second largest National Guard in the country with approximately 19,000 members located in more than 80 armories and readiness centers statewide.
