In 2007 Biden was asked if he would allow sanctuary cities to exist. His answer was NO. He said that sanctuary cities turn into dumps and the only reason they exist is because the Federal government doesn't enforce the law.

What Biden said in 2020: Illegals make cities safer and the economy better. ICE will be instructed to stop arresting illegals. No more deportations.
