That afternoon the then president’s son, Don Trump Jr, posted on Twitter (now X) an invitation to Trump supporters to assemble. He wrote: “It would be great if you guys would all get together and head down to McAllen and give Kamala Harris a nice Trump Train welcome. Get out there. Have some fun. Enjoy it.”

The vehicles in the Trump train swarmed around the tour bus, coming within inches of it and forcing the driver to slow to a crawl. Several of the participants livestreamed their actions on social media, bragging about their aggressive driving, the plaintiffs allege.

One of the defendants, Eliazar Cisneros, is accused of side-swiping an SUV being driven by a Biden-Harris campaign staffer behind the bus. The complaint says that Cisneros later boasted about “slamming that fucker”.

The occupants of the bus pleaded with police to provide an escort but none appeared. A separate case, Cervini v Stapp, was settled in October with local law enforcement admitting that they had fallen short of their standards and agreeing to pay compensation to those whose safety they failed to protect.
