Rick Santiago stood on Constitution Avenue NW on Friday morning, his cellphone camera panning across dozens of truck drivers blasting their air horns in a wake-up chorus that could be heard all the way to the White House.

Santiago, who organized the 8 a.m. protest, was streaming video to thousands of viewers online as the convoys of trucks he rallied arrived to deliver to the nation’s leader what he called the distress call over shipping rates the truckers say are now so low they can’t make a living.
