The FBI is investigating an Omaha man accused of threatening Democratic U.S. Senate candidate Bob Kerrey in an email to a political action committee.
But 68-year-old Laurence McCabe says he never planned to harm anyone.
McCabe says his frustration with a televised political ad attacking Republican U.S. Senate candidate Deb Fischer led him to send the Aug. 7 email to End The Gridlock political action committee, which ran the ad.
McCabe asked in the email if he had the group's permission to "put bullets in Democrat heads" to end congressional gridlock and suggested Kerrey might be among those Democrats.
McCabe says the email was "not serious," but the FBI has filed a criminal complaint against him. McCabe has been released on bond.
