City Commissioner Seth Bluestein, a Republican, responded on X that there was “absolutely no truth” to the charge, calling it “disinformation”.
Polls for weeks have shown a razor-thin race between Democratic Vice President Harris and Republican Trump, 78, who would be the oldest president at the time of inauguration, the first felon president and only the second to serve non-consecutive terms.
The Harris campaign reported strong turnout in Philadelphia including among Puerto Ricans, who were disparaged by a comedian at a Trump rally a week earlier.
An early exit poll by NBC News showed that the most important issue for voters was democracy – a signature issue for Harris – even more than the economy.
Harris, 60, would also be only the second Black and first person of South Asian descent to be president.
