Suspect not actively cooperating with authorities, acting attorney general tells CBSpublished at 13:56 BST
A bit more now from Acting US Attorney General Todd Blanche, who has been speaking to multiple US media outlets on Sunday.
In an interview with CBS News's Face the Nation, he reiterates previous comments that investigators believe the suspect was targeting members of the Trump administration.
He adds that the suspect is not actively cooperating with authorities.
Blanche tells CBS that investigators believe the suspect was staying at the Washington Hilton, where the event was being held, and travelled to Washington by train - initially travelling from Los Angeles to Chicago, before heading on to the capital.
