Trump warns of 'rigged election' as he uses conspiracy and fear to counter Biden's convention week

Elsewhere in his speech, Trump said he should be granted a "redo" on his first term, alleging falsely that his first campaign was spied upon by the previous administration. And at another point, he joked that he may remain in office for "16, 20" years.

Though made in jest, those remarks only fuel the impression that Trump is preparing, at a minimum, to challenge November's results if they do not show him winning. Taken together, the remarks suggest Trump is actively working to undermine the results of an election that polls currently show him losing.
