A motorcyclist was arrested on June 21 after a video (below) showed him driving through a group of protesters.
The clip shows the moment the driver rode his bike through a group of protesters outside of San Francisco's Federal Building, who were staging a "die-in," lying on the street in protest of the Republican Party's new health care bill, according to KPIX.
No one was reported injured, and the man was arrested, though police have not said what his charges will be.
The motorist drove the red motorcycle the wrong way on the street, going relatively slowly, but still loudly, scaring the protesters.
"Everyone thought he was just confused, but he didn't stop, and at some point it became clear he was going to come through the crowd and people jumped out of the way," said Emily Lee, a spokeswoman for the group, Bay Resistance.
Bay Resistance and Senior and Disability Action organized the event, so many of those protesting were elderly or disabled, Daily Mail reports.
"He was definitely targeting us," added Lee. "It was unclear if it was for political reasons or if he was just mentally unstable or what, but it was terrifying."
Authorities stopped the man, with a federal police officer pulling out a gun when he failed to comply with an order to get off of his motorcycle.
Police did not release the man's identity, but according to reports, the motorcycle is registered to Jeffrey Dillon.
Dillon is listed on Facebook as helping to run a group called White Privilege Club.
Senate Republicans revealed the health care bill on June 22, after a period of secrecy surrounding its contents, CNN reports.
"It's going to be very good," said President Donald Trump of the bill. "A little negotiation but it's going to be very good."
The newly revealed bill would reportedly repeal the Affordable Care Act's individual mandate, reduce funding for Medicaid and slash taxes for insurers. It would keep ACA subsidies in place, giving people help with paying for individual insurance coverage.
The bill will also defund Planned Parenthood for one year, if it passes.
Doctors' groups have spoken out against the bill, urging the Senate to reject it, according to The Wall Street Journal.
The American Psychiatric Association said the bill "rolls back Medicaid expansion, caps the Medicaid program significantly ... and removes protections for people with pre-existing health conditions."
Shatterproof, an organization that works to help those with substance abuse problems, said the bill would have "devastating effects for Americans with substance use disorders."
The American Lung Association also spoke out against the bill, saying that "any healthcare legislation must be adequate, affordable and accessible. This bill fails to meet this standard."
