Sanctuary City Funding Disputes (2017-2020)
The Trump administration attempted to withhold federal Justice Department grants from sanctuary cities (including New York, Chicago, and San Francisco) unless they cooperated with immigration enforcement.
Federal courts repeatedly blocked the funding restrictions, ruling the administration lacked statutory authority to impose the new conditions.
The rulings reinforced that federal grants given for one purpose cannot be unilaterally revoked for unrelated policy disagreements.
Directly parallels Boston's case—a federal agency attempting to revoke already-awarded funds to coerce local policy alignment, with the outcome hinging on statutory authority.
