The Facts About the Attack on Paul Pelosi, According to Prosecutors

The attack on Paul Pelosi, the husband of House Speaker Nancy Pelosi, has not only raised alarm about the threat of violence to elected officials and their families, but also become the focus of baseless conspiracy theories propagated by a litany of Republicans and conservatives.

After state and federal charges were filed against a suspect, the San Francisco district attorney, Brooke Jenkins, said that the widespread misinformation had made it all the more important for prosecutors to present the facts to the public.

Here is what we know about the Oct. 28 attack at the speaker’s San Francisco home, based on court documents and accounts provided by officials.

The attack began with a break-in.

An affidavit from an F.B.I. agent that accompanied the federal charges and a filing by local prosecutors have provided a chilling narrative of the break-in. They outline a groggy early-morning home invasion that culminated with a single, sudden hammer blow, delivered in the presence of shocked police officers.
