Liz Cheney speech: 'Ignoring the lie emboldens the liar'

Liz Cheney delivers an impassioned House floor speech on the eve of a vote by colleagues to oust her from a party leadership role.

She has pilloried former President Donald Trump for falsely claiming the 2020 US election was stolen.

"We must act to prevent the unravelling of our democracy," said the Wyoming lawmaker.
