The Senate votes tomorrow on a bill that would deny federal law enforcement funding to sanctuary cities, which protect undocumented immigrants from being deported. Los Angeles and San Francisco are both sanctuary cities. The bill would also put stricter prison sentences on those who try to re-enter the United States after being deported. The House passed its version of this bill in July, after the death of Kate Steinle, a woman in San Francisco who was shot and killed by an undocumented immigrant. That immigrant had been released from jail instead of handed over to federal immigration officials.
