If you want to see who pays for all these illegal aliens, look in the mirror ... your local, state, and Federal taxes pay for and subsidize services - shelter, food, mediciine, education, legal services - for illegal aliens.
The most expeditious way to offlload local and state costs is to bus them to another state and municipality.
Only when Dem Governors, Dem Mayors, Dem Reps, and Dem Senators suffer the costs - in their budgets or at the ballot box - will things change.
Boston and Massachusetts are happy to be a Sanctuary City and a Sanctuary State so long as its really El Paso and Arizona that have to suffer the day-to-day, real world and budgetary consequences.
I'd like to see a GOP majority withold Federal transportation and welfare funds from non-compliant sanctuary states and municipalities.
DeSantis is getting much press for passing a state law that requires state employers to comply with existing Federal requirements (per the 1987 Immigration Reform Act) to verify the legal immigration status of new hires.
The Feds will not enforce their own Immigration laws; so state governments have to hold their employers to account instead.
