Senators at Donald Trump's second impeachment trial have been shown new dramatic and graphic video of the day his supporters stormed the US Congress.
The footage showed police engaging in hand-to-hand clashes with rioters and desperately pleading for support.
Officers ushered politicians to safety, sometimes within metres of the mob breaking into the chambers.
Using Mr Trump's own words and tweets, Democrats prosecuting the case argued he had acted as "inciter in chief".
A two-thirds majority is required to convict Mr Trump in the evenly split 100-seat Senate, but an acquittal looks likely as the vast majority of Republican senators have remained loyal to him so far.
However, if convicted, he could be barred from holding office again.
