The FBI is investigating a shooting that took place last month at a North Carolina home belonging to the parents of Pat Harrigan, a former Green Beret and Republican candidate running for Congress, according to reports.

WBT News reported Thursday that the FBI is involved in the investigation. The agency could not be reached for confirmation. 

Harrigan’s campaign manager told The Carolina Journal that a suspect shot into the home of his parents in Hickory. He said Harrigan’s children were in the home at the time and the shot entered just a few feet from where they were sleeping. 

Harrigan's campaign told Fox News Digital his children often spend the night at the house, but he was not there at the time of the shooting. 

As of Thursday, there have been no arrests in the incident. Harrigan’s campaign has not confirmed that the FBI is involved in the investigation.

Harrigan is running against Democrat state Sen. Jeff Jackson in North Carolina’s 14th congressional district. 

In a statement Thursday, Harrigan said his opponent’s politics have led to "rising inflation, economic ruin, & rampant crime—including political violence.

"My mission is a better economy, less inflation & safe streets. A bullet & death threats aren’t enough to knock this Green Beret off that mission." 

Harrigan's campaign confirmed to Fox News Digital that the race had gotten so heated that he started wearing a bulletproof vest to campaign events and had received death threats. 

The shooting comes amid heightened concerns for the security of politicians. The Department of Homeland Security and other law enforcement agencies, including the FBI, issued an intelligence bulletin on Friday warning that political candidates, election officials and the public faced a heightened risk of violence.

Those warnings were underscored by a violent attack on House Speaker Nancy Pelosi’s 82-year-old husband at their San Francisco home early Friday morning.
