Police arrested at least 35 people Friday at a San Diego rally for Donald Trump. About 1,000 people turned out to protest the hard-line immigration policies of the presumptive Republican presidential nominee, Reuters reports. Clashes between protesters and supporters were largely non-violent, but police in riot gear began pushing and pepper spraying protesters. .@SanDiegoPD- Fantastic job on handling the thugs who tried to disrupt our very peaceful and well attended rally.
