BOISE, Idaho (AP) — Anti-government activist Ammon Bundy has been arrested after failing to attend his trial on charges that he trespassed during an Idaho legislative session last fall.

Bundy didn't appear in the courtroom Monday because he was protesting outside the building instead, apparently angry in part over mask requirements put in place during the coronavirus pandemic.

Bundy was joined by about two dozen other protesters and was one of three people arrested during the demonstration.

Bundy is representing himself in his trespassing case and says he doesn't believe his actions at the Idaho Statehouse were illegal. He gained international attention during a 2016 armed standoff at an Oregon wildlife refuge.
