This administration's Secret Service White House detail has made a laughing stock of the agency, which is unfortunate.
I'm guessing that SS at the White House is considered an elite assignment, no sweat since there is a fence around the place, and cameras, and supposedly somebody watching the cameras, and they've lapsed into plum laziness, staring into their cell phones non-stop.
Bad for the other guys who have the dangerous assignments, protecting the pres/family when they are out and about, etc.
Again, just my guess. No need to argue with me. I'm probably way off base.
