The 6 January discovery of the pipe bombspublished at 14:20 GMT
As rioters began to storm the US Capitol on 6 January, a passerby a couple of blocks away discovered two pipe bombs.
They had been placed outside the Democratic National Committee and Republican National Committee headquarters the night before, authorities later confirmed.
According to a report obtained by the BBC’s US partner CBS News, the bombs had one method of detonation: a 60-minute kitchen timer. But they ultimately did not detonate for unknown reasons.
The pipe bombs were safely deactivated by authorities, and investigators launched a large-scale campaign to find the person responsible, offering a reward of $500,000 (£402,000) and releasing detailed maps, photos, and videos to the public.
