Trump warms up for debate by threatening to jail election officials

Donald Trump limbered up for his debate with Kamala Harris by showing the extremism that risks playing into the vice president’s claim that he’s an “unserious man” who is an “extremely serious” threat if he’s returned to the White House.

Trump warned he will jail election officials he considers cheats; is complaining Pennsylvania’s voting is a fraud; vowed to pardon January 6 rioters; railed against women who accused him of sexual misconduct; and spent hours in recent days on sometimes incoherent rants that raised questions about his state of mind.
