May 14th POTUS interview with Maria Bartiromo. Truckers laying on the horns can be heard. POTUS stops to acknowledge all the noise. If you start at 8:00 minute mark you can really hear em loud in the background, then he addresses the noise. Maria calls them trucking protesters.

So, 2 days in a row, truckers blowing their horns in ear shot of the WH. "Hundreds of trucks"

They obviously knew when they set up the presser outside that the horns were going to be audible. During questioning, the mic aimed at reporters picks up the horns obnoxiously well.

Trump says they are not protesters, they are supporters. Need some "we are the news now DC anons" to get some eyes on footage.
