They also confirmed the home where the warrant was executed belongs to billionaire and former California gubernatorial candidate Stephen Cloobeck.
Earlier this year, Swalwell ended his campaign for California governor and resigned from Congress after multiple women accused him of sexual assault. He has denied those allegations.
Swalwell had been staying with Cloobeck at some point earlier this year, but Cloobeck said he kicked him out following the allegations.
Cloobeck was a former supporter of Swalwell.
