The FBI has reportedly found no evidence that far-right allies of Donald Trump conspired to overturn the presidential election during the January 6 assault on the US Capitol, according to law enforcement officers briefed on the investigation.
Reuters reported the FBI doesn’t believe the thousands-strong mob that stormed the Capitol was part of a coordinated effort, or that the rioters had planned what they would do once they breached the building.
The story was immediately seized on by supporters of Mr Trump as evidence that the mob that smashed their way into the Senate chamber had not been trying to prevent the certification of the 2020 presidential results.
However, other commentators pointed out that the FBI investigation overlooked the fact dozens of members of far-right militias are facing conspiracy charges relating to the riot.
