In San Jose, California, on Thursday night, anti–Donald Trump protesters clashed with supporters of the presumptive Republican nominee.

The melee began after a Trump rally ended and supporters began to head to their cars. MSNBC's Jacob Rascon reports he witnessed several protesters rush up to a woman wearing a Trump jersey. They taunted her, he said, and threw things at her, including eggs. He also said he saw several people burning Trump merchandise, including his "Make America Great Again" hats.

Fusion's Tim Pool filmed one protester as he ran up behind a supporter and hit him with a bag; the supporter, with blood dripping down his face, said he was chased, spit on, and called a "racist." On Twitter, BuzzFeed's John Stanton said it appears that police officers on the scene are "focused on protecting businesses and property," but not the Trump supporters who ended up in the middle of the protest.

UPDATE: After about 90 minutes staying in position around the San Jose Convention Center, police moved in to break up the melee, and one officer was assaulted, according to the San Jose Police Department. At least four people were taken into custody. There were no reports of serious injuries or major property damage, police said. Catherine Garcia
