The fact that some left-wing activists decided to follow Democratic Arizona Sen. Kyrsten Sinema into the bathroom while recording her is gross. But it really isn’t much of a surprise. A segment of left-wing activists has made harassing political opponents a regular exercise.

The activists who followed Sinema into a bathroom while pressing her for not supporting President Joe Biden’s $3.5 trillion spending plan were part of the activist group Living United for Change in Arizona. A collection of activists last month also hounded Democratic West Virginia Sen. Joe Manchin at his houseboat over his opposition to the $3.5 trillion plan. They came from a collection of groups, including Greenpeace USA and CASA, which the Hill describes as “the largest grassroots immigrant advocacy organization in the mid-Atlantic area.”
