In videos posted on Twitter,a group of cars and pickup trucks – many adorned with large Trump flags – can be seen riding alongside the campaign bus on Friday,and at times boxing it in,as it travelled from San Antonio to Austin. At one point,one of the pickup trucks can be seen colliding with an SUV that was driving behind the bus.
Neither Biden nor his running mate,Kamala Harris,were aboard the bus. The Democratic campaign cancelled an event later in the day.
