The crowd grew in numbers along First Avenue SE, as rush hour was underway. Motorists honked their support, leading to cheers from the crowd.

Trump’s appearance coincided with Democratic presidential nominee Hillary Clinton’s acceptance speech  at the Democratic National Convention in Philadelphia.
