"In these political dark ages, it's important for us to stand up for one another," Morello told MTV News earlier in the day. "These hotel workers by the airport make 20 percent less wages than hotel workers around the rest of Los Angeles. We're here to express our solidarity with them, to help them unionize and to help them close the gap between their sub-poverty wages and the millions and millions of dollars the people who own these hotels make."

Morello said that many of the protesters went into the event expecting to be arrested. Approximately 2,000 people in total participated. Singer Ben Harper also performed a three-song set at the rally and participated in the protest, but was not among those arrested.

According to MTV.com, the arrested protesters were expected to spend 24 hours in police custody.
