Protesters, some burning the American Flag as they waved the Flag of Mexico, physically attack, punch, throw eggs at Trump supporters in San Jose - And the politicians let them while the police did NOTHING! Had this been white people attacking Obama & his supporters, the wrath of the full federal, state, county & local law enforcement would have stopped in in SECONDS!

A group of protesters attacked Donald Trump supporters who were leaving the candidate's rally in San Jose on Thursday night. A dozen or more people were punched, at least one person was pelted with an egg and Trump hats grabbed from supporters were set on fire.

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 Thursday night. One officer was assaulted, police Sgt. Enrique Garcia said.

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, had thinned significantly. Still, those that remained, filling about a city block near the San Jose Convention Center, were rowdy and angry.

Some banged on the cars of Trump supporters as they left the rally and chased after those on foot to frighten them.
