SAN JOSE, Calif. — Donald Trump supporters leaving the candidate’s rally in San Jose were pounced by protesters. A dozen or more people were hit and car windows were broken. Trump hats grabbed from supporters were set on fire. At least one woman was hit by an egg.

Police stood their ground at first but after about 90 minutes moved into the remaining crowd to break it up and make arrests. At least four people were taken into custody, though police didn’t release total arrest figures. One officer was assaulted.

There were no immediate reports of injuries and no major property damage, police said.

The crowd, which had numbered over 300 just after the rally, thinned significantly as the night went on, but those that remained near the San Jose Convention Center were rowdy and angry.

Police were keeping their distance from the crowd as the scuffles played out, but keeping them from getting any closer to the convention center.
