Republican Rep. Trey Gowdy had a gun pointed at him Sunday while picking up his daughter from church, police said.
The suspect, reportedly identified as a 52-year-old woman, was arrested after the incident.
The South Carolina congressman's office confirmed the account but offered few details about the threat beyond thanking the police in Spartanburg, S.C., who assisted.
"Mr. Gowdy is grateful to the Spartanburg Public Safety Department for their help last night and especially for helping make sure his daughter was safe," spokesman Josh Dix said.
Police later issued a statement saying the suspect walked up to Gowdy's vehicle "displaying a handgun" while he was waiting in the church parking lot. She twice told him to "stop following me," police said, though he explained he was just waiting to pick up a family member. According to police, Gowdy then put his car in reverse as the suspect "started running after him on foot across the parking lot."
Gowdy reported the incident to police, who then arrested the suspect.
Gowdy's office indicated Monday that the suspect would be prosecuted.
