Ohio Rep. Max Miller said he was "run off the road" on Thursday in Rocky River, Ohio, by a driver who showed him a Palestinian flag and threatened him. "Some unhinged, deranged man decided to lay on his horn and run me off the road when he couldn't get my attention, to show me a Palestinian flag, not to mention death to Israel, death to me, that he wanted to kill me and my family," Miller, a Republican, said in a videoposted on X. The congressman, who is Jewish, called it "blatant antisemitic violence." Miller said on X he reported the issue to local authorities and the U.S. Capitol Police, adding, "We know who this person is." The Rocky River Police Department in Ohio confirmed to CBS News that the incident was reported, but did not provide any further details. Capitol Police did not immediately respond to a request for comment. Rocky River is a suburb of Cleveland. The congressman did not elaborate on the alleged threats. CBS News has reached out to Miller's office for additional details. Threats against lawmakers and otherpublic officials, including judges and prosecutors, have risen in recent years, Capitol Police and the U.S. Marshals Service say. The U.S. Capitol Policesaysit investigated 9,474 "concerning statements and direct threats" against members of Congress and their families and staff last year, up from around 8,000 the year prior. The concerns were amplified after Minnesota state Rep. Melissa Hortman and her husband Markwere fatally shotover the weekend, and state Sen. John Hoffman and his wife were injured in a separate shooting. The suspect, Vance Boelter, wascharged in the shootings, and authorities say they found a list of names and addresses for other public officials in the suspect's SUV. House Democratic leaders said in astatement, "We condemn in the strongest possible terms the attack on Congressman Max Miller and his family and are thankful they are safe. The rise in political violence in this country is unacceptable." CBS News has reached out to House Speaker Mike Johnson's office for comment.
