On Oct. 23, 2018, President Joe Biden’s son Hunter and daughter in law Hallie were involved in a bizarre incident in which Hallie took Hunter’s gun and threw it in a trash can behind a grocery store, only to return later to find it gone.

Delaware police began investigating, concerned that the trash can was across from a high school and that the missing gun could be used in a crime, according to law enforcement officials and a copy of the police report obtained by POLITICO.

But a curious thing happened at the time: Secret Service agents approached the owner of the store where Hunter bought the gun and asked to take the paperwork involving the sale, according to two people, one of whom has firsthand knowledge of the episode and the other was briefed by a Secret Service agent after the fact.

The gun store owner refused to supply the paperwork, suspecting that the Secret Service officers wanted to hide Hunter’s ownership of the missing gun in case it were to be involved in a crime, the two people said. The owner, Ron Palmieri, later turned over the papers to the Bureau of Alcohol, Tobacco, Firearms, and Explosives, which oversees federal gun laws.
