The FBI has found scant evidence that the January 6 attack on the US Capitol was the result of an organized plot to overturn the presidential election result, according to four current and former law enforcement officials.
Though federal officials have arrested more than 570 alleged participants, the FBI at this point believes the violence was not centrally coordinated by far-right groups or prominent supporters of then-President Donald Trump, according to the sources, who have been either directly involved in or briefed regularly on the wide-ranging investigations.
A former senior law enforcement official with knowledge of the probe said that '90 to 95 percent of these are one-off cases.'
FBI investigators did find that cells of protesters, including followers of the far-right Oath Keepers and Proud Boys groups, had aimed to break into the Capitol.
But they reportedly found no evidence that the groups had serious plans about what to do if they made it inside.
Prosecutors have filed conspiracy charges against 40 of those defendants, alleging that they engaged in some degree of planning before the attack.
They alleged that one Proud Boy leader recruited members and urged them to stockpile bulletproof vests and other military-style equipment in the weeks before the attack and on Jan. 6 sent members forward with a plan to split into groups and make multiple entries to the Capitol.
