The scene inside the San Diego Convention Centre during Trump’s speech was relatively placid, while outside demonstrators opposed to his controversy-ridden White House bid marched and chanted, carrying signs criticizing his rhetoric against illegal immigration.
Waving the US and Mexican flags, more than 1,000 people turned out for anti-trump rallies in San Diego, a city on the US-Mexico border whose San Ysidro port of entry sees nearly 300,000 people a day cross legally between the countries.
San Diego is considered a bi-national city by many who live and work on opposite sides of the border, and about a third of the city’s population is Latino.
During Trump’s speech, some protesters outside the convention centre scaled a barrier and lobbed water bottles at police. One man was pulled off the wall and arrested as others were surrounded by fellow protesters and backed away from the confrontation.
After the convention centre emptied, clusters of Trump supporters and anti-Trump demonstrators began to mix in the streets, many exchanging shouted epithets and some throwing water bottles at one another.
Police in riot gear declared the gathering an unlawful assembly and ordered the crowd to disperse, herding the crowd out of the city’s hotel and restaurant-filled Gaslamp Quarter.
San Diego police said on Twitter that 35 arrests were made during the protest. No property damage or injuries were reported, police said.
“Fantastic job on handling the thugs who tried to disrupt our very peaceful and well attended rally,” Trump tweeted to police afterwards.
