Political leaders from both parties condemned Friday’s attack against House Speaker Nancy Pelosi’s husband, the latest in a string of incidents affecting members of Congress and their families this year. Though the assailant’s motive is still under investigation, several lawmakers have blamed hyperpartisanship and divisive political rhetoric for an increase in political violence and security incidents in recent years. Those factors also contributed to the Jan. 6, 2021, attack on the U.S. Capitol. Capitol Police has seen a steady rise in threats, which more than doubled annually from 3,939 in 2017 to 9,625 last year. Through March 23 this year, Capitol Police said it has opened about 1,820 cases, including concerning statements and threats.
