Capitol attack: Cheney says Republicans must choose between Trump and truth

On a day of alarming polling about attitudes to political violence and fears for US democracy, and as the first anniversary of the Capitol attack approached, a Republican member of the House committee investigating the events of 6 January 2021 had a stark warning for her party.

Trump supporters attacked Congress in an attempt to stop certification of his defeat by Joe Biden, which Trump maintains without evidence was the result of electoral fraud. Five people died around a riot in which a mob roamed the Capitol, searching for lawmakers to capture and possibly kill.

On Sunday, Cheney and Bennie Thompson of Mississippi, the committee chairman, again discussed the possibility of a criminal referral for Trump over his failure to attempt to stop the riot or for his obstruction of the investigation.

Sunday saw a rash of polls marking the anniversary of 6 January.

CBS found that 68% of Americans saw the Capitol attack as a sign of increasing political violence, and that 66% thought democracy itself was threatened.

When respondents were asked if violence would be justifiable to achieve various political ends, the poll returned an average of around 30%. A survey by the Washington Post and the University of Maryland said more than a third of Americans said violence against the government could be justified.

ABC News and Ipsos found that 52% of Republicans said the Capitol rioters were trying to protect democracy.
