A protester in California appeared to snatch off a federal agent's mask during an altercation last week, according to new footage.

Two Senate Democrats are working to stop ICE agents from wearing masks while making arrests. The Trump administration says it protects the agents, while some lawmakers are saying it creates panic and fear.

An ICE spokesperson told CBS New York the masks are optional but that "ICE law enforcement and their families are being targeted and are facing a 500% increase in assaults ... due to the demonization of ICE by hostile groups and irresponsible elected officials."
