President Donald Trump on Sunday mockingly claimed that his supporters were “protecting” a campaign bus belonging to Democratic presidential nominee Joe Biden when a caravan of vehicles dangerously surrounded it on a Texas highway, leading to a vehicular collision.

“They were protecting their bus yesterday because they’re nice,” Trump said at a rally in Michigan to cheers, laughter and applause.

Video that captured the situation in Hays County on Friday showed the tour bus being surrounded by vehicles with Trump flags.
