The US Capitol Police investigated 7,501 threats against members of Congress last year, according to new figures released Tuesday.

Last year’s numbers marked the first decline in at least five years, but they remained «historically high,» nearly double the 3,939 cases investigated in 2017, Capitol Police said. In 2021, when the riots took place on January 6, the cases of threats increased to 9,625.

“Threats against members of Congress remain too high,” US Capitol Police Chief Tom Manger said in a statement. “This has resulted in a necessary expansion, not only of our investigative capabilities, but also of our protection responsibilities.”

The tallies include investigations into «troubling statements and direct threats,» and police said the number of threats against Democrats and Republicans has been similar, noting that all members of Congress have been affected.

An intruder was charged with breaking into the San Francisco home of former House Speaker Nancy Pelosi, D-Calif., in October and assaulting her husband with a hammer. Police said the shooter later said he was looking for Pelosi, who was in Washington, DC, at the time.

Weeks after that attack, a Michigan man was arrested and charged with threatening to kill Rep. John Garamendi, another California Democrat, and FBI Director Christopher Wray.

Most recently, a Washington man was charged with seven counts of making interstate threats after being accused of leaving more than 400 voice messages for members of Congress over two years.

Threats of political violence have also spread to the state and local levels. Solomon Pena, an unsuccessful Republican candidate for the New Mexico state House of Representatives, was arrested Monday in connection with four shootings at the homes of two county commissioners and two state legislators.
