Some government agents are hurting people in big cities. A leader in San Francisco saw this. She did not like what she saw. She wanted to protect the people in her city.
The leader made a new plan. Her plan uses the local police. The police in California work for the state, not the whole country. They protect the people who live there.
The plan says that local police can arrest federal agents. This can only happen if the agents break California's laws. Nancy Pelosi, another important leader, agrees with this plan. She said that state laws are important for everyone to follow.
