"If she told the 'truth,' he would let her go, but if she 'lied,' he intended to break her kneecaps — forcing her to be wheeled into Congress as a lesson to other Democrats, Mr. DePape told police officers in an interview.
He had 'a roll of tape, white rope, a second hammer, a pair of rubber and cloth gloves, and zip ties' according to the U.S. attorney’s office for the Northern District of California, which filed the charges."
From "Intruder Wanted to Break Speaker Pelosi’s Kneecaps, Federal Complaint Says/Federal prosecutors filed charges on Monday against the man the police said broke into House Speaker Nancy Pelosi’s San Francisco home and struck her husband with a hammer" (NYT).
"The swift action by the Justice Department in bringing federal charges — on the same day the San Francisco District Attorney’s Office was expected to file its own charges against Mr. DePape — reflects the department’s urgency in addressing what it sees as a politically motivated crime shortly before the 2022 midterm elections. There has been a surge in threats and attacks against figures of both political parties in recent years, and Ms. Pelosi, in particular, has long been the subject of vilification and threats."
ADDED: Here's the criminal complaint. It's worth noting that DePape spoke to the police and revealed his plot to question Nancy Pelosi and to break her kneecaps if she lied, which he expected her to do. Also, he was not dressed in underpants, but shorts, and he had a large backpack and quite a few supplies, including the hammer we've heard so much about. He is alleged to have broken the window next to the door handle and to have found Paul Pelosi in his bedroom, in bed.
Also: "DEPAPE stated he wanted to tie Pelosi up so that DEPAPE could go to sleep as he was tired from having had to carry a backpack to the Pelosi residence.... DEPAPE explained that he did not leave after Pelosi’s call to 9-1-1 because, much like the American founding fathers with the British, he was fighting against tyranny without the option of surrender."
