Biden says Harris would be 'historic, pro-union president' at Labor Day rally

US President Joe Biden gave Vice President Kamala Harris a robust endorsement at a Labor Day rally, telling that she's more than capable of leading the count union workers, during their first joint campaign appearance.

Seeking to shore up her support from blue-collar voters, Harris opted to campaign alongside Biden on Monday in Pennsylvania and wade into a fight over the ownership of one of America’s largest steel producers. Her Republican opponent, former President Donald Trump, and his running mate stayed off the campaign trail on Monday.
