While his costume was colorful, prosecutors said his intentions were dark. In an 18-page document that was submitted in court on Thursday, prosecutors said Mr. Chansley approached a Capitol Police officer and screamed that members of the mob “were there to take the Capitol and to get congressional leaders.”
Mr. Chansley, a fixture of the QAnon conspiracy movement known as the “Q Shaman,” wrote a note to Mr. Pence, reading, “It’s only a matter of time, justice is coming.”
On Friday, Magistrate Judge Deborah M. Fine of Federal District Court in Phoenix denied bail to Mr. Chansley, saying he was “an active participant in a violent insurrection to overthrow the United States government.” When Mr. Chansley requested to speak, Judge Fine told him it was “not advisable.”
In Texas, a federal prosecutor said another suspect, Lt. Col. Rendall Brock Jr., planned to take hostages with zip-tie handcuffs when he stormed the Capitol last week, and the lawyer pointed to violent online threats that Mr. Brock made in the run-up to the mob attack.
Steven M. D’Antuono, the head of the F.B.I.’s Washington Field Office, said the public provided the F.B.I. with about 140,000 digital tips, noting that friends and family members had turned in rioters and advised people involved in the violence to surrender before the F.B.I. found them.
“If this investigation was a football game,” Mr. D’Antuono said, “we would still be in the first quarter.”
