Roughly 100 people waved signs and danced in protest outside a Tesla dealership in Washington on Saturday, angry at the electric vehicle maker's billionaire CEO Elon Musk, who has led efforts to sharply cut the federal workforce.

Just after the protest started, a man drove his SUV into the crowd, claiming his brakes had failed. Police said he will be charged with assault.

Hundreds of protesters gathered outside the Tesla showroom in the Meatpacking district of Manhattan today as a part of the “Tesla Takedown” movement.

Elon Musk, the world's wealthiest person, was enraged after The New York Times reported he would receive a Pentagon briefing on China war plans.
