A police officer who interviewed David DePape told the hearing that President Joe Biden’s son Hunter and Democratic California Governor Gavin Newsom were also on the suspect’s “hit list”.
Mr DePape is facing six charges, including attempted murder, for the 28 October incident. He pleaded not guilty to all counts last month.
At the end of Wednesday’s nearly four-hour hearing, San Francisco Superior Court Judge Stephen Murphy ruled there was enough evidence for the trial to proceed.
Officers testified about how they responded to the attack on Paul Pelosi at the family home in the California city.
According to prosecutors, the defendant had planned to hold Mrs Pelosi hostage, but she was in Washington DC at the time.
The emergency call placed by Mr Pelosi, 82, was played to the court.
According to KRON4 News, the 911 audio suggested Mr Pelosi did not know Mr DePape.
The dispatcher asked: “Do you know who the person is?”
“No, I don’t know who he is,” Mr Pelosi responded.
Police Sgt Kyle Cagney testified that he had arrived at the house seconds before Mr DePape swung the hammer on to Mr Pelosi’s head, cracking his skull.
The officer displayed the weapon to the court.
