The scene outside a Donald Trump campaign rally in Albuquerque, N.M., turned violent on Tuesday, leading to at least one arrest and several injuries, police say.
According to the Albuquerque Police Department's Twitter feed, several officers were hit by rocks thrown by protesters. The police later characterized the clash as a "riot."
NPR's Sarah McCammon was at the Trump rally, which was held in the Albuquerque Convention Center. She filed this report for our Newscast:
"Reporters are being told to stay inside because of protesters outside. ... There is a broken window. There's glass that shattered with some metal barriers that have been set up around it. ... Lots of police, we've seen several riot police on riot horses riding by outside."
Protesters carried anti-Trump banners, toppled barricades and threw plastic bottles and burning T-shirts at police, The Associated Press reports. Officers responded with smoke grenades and pepper spray, according to multiple news reports.
Several protesters inside the venue chanted slogans and were evicted by police and security guards. Trump mocked them, telling them to "go home to mommy." The candidate's supporters chanted, "Build that wall!"
New Mexico Gov. Susana Martinez, who is chairman of the Republican Governors Association, has not endorsed the de facto Republican presidential nominee and did not attend the rally. During his speech, Trump criticized Martinez's performance as governor, claiming the state under her leadership has seen an increase in the number of food stamp recipients.
Trump was holding a rally in New Mexico as part of a campaign swing through the western U.S., focusing on states with upcoming primaries — New Mexico, California and Montana among them. He doesn't have a Republican rival to beat anymore, but he's looking to build voter support and gather money and data along the way.
It's not the first time a Trump campaign event has erupted in violence. Less than a month ago, as NPR reported, about 20 people were arrested outside the Pacific Amphitheater in Costa Mesa, Calif. There were no injuries at that event, but a police car was attacked by demonstrators, who shattered the car's windows.
