Sen. J.D. Vance (R-OH) reflected on the “bittersweet” rally former President Donald Trump conducted in Butler, Pennsylvania, over the weekend as the late Corey Comperatore could not join the other attendees.

Comperatore was killed in Trump’s July 13 rally in Butler while shielding his family from gunfire that injured two other rally attendees. Vance, Trump’s vice presidential nominee, said there was “tension” among attendees at the rally over the weekend between the feelings of being glad to see Trump back and being mournful over how Comperatore was killed at the previous Butler rally.
