Oregon’s congressional delegation: Portland demonstrator wounded by U.S. Marshals Service tactical unit member

The lawmakers demanded to know more about the federal government's response to protests that have roiled Portland nightly for nearly two months. They said they are especially concerned that the Marshals Service and other federal agents working the protests are taking direction from federal officials outside of Oregon.

"Their presence and lack of coordination raises urgent concerns about how those engaging in illegal use of force against demonstrators will be held accountable," U.S. Sens. Ron Wyden and Jeff Merkley, and U.S. Reps. Earl Blumenauer and Suzanne Bonamici, all Democrats, wrote in a letter to U.S. Attorney General William Barr and Acting Homeland Security Secretary Chad Wolf.

The letter was spurred by an incident Saturday night in which a deputy U.S. Marshal fired across a street on a demonstrator identified as Donavan LaBella, critically wounding the man.
