A top Republican is calling on FBI Director Christopher Wray to take the “threat of pro-abortion violent extremism” seriously when investigating the targeting of anti-abortion groups and to brief the Senate on the bureau’s efforts “to combat this wave of abortion-related violence.”

Sen. Chuck Grassley (R-IA), the ranking member on the Senate Judiciary Committee, raised the topic with Wray in a letter this week following the Supreme Court overturning Roe v. Wade and returning the regulation of abortion laws to the states on Friday.
