The truckers’ grievances are numerous and varied. They include what they say are unfairly low freight rates during the coronavirus pandemic, price-gouging by the brokers, ill-conceived safety regulations and permissive federal attitudes toward the autonomous vehicles that threaten their occupation.

Greg Anderson, who said he has been in the trucking business for 33 years, told CNN earlier on Friday that Trump had “lied on national television” with his remark to Bartiromo about how the protesters are not protesters at all.

“This is a protest,” Anderson said. “Mr. Trump elaborated that we were here to support him. Our message to him would be this is a protest against bad regulation, broker transparency, truck insurance, so on and so forth. This is not here to support Trump. We’re here to get resolution and bring awareness to our problem and fix our problems.”
