Democrats in the U.S. Senate aided Republicans in advancing the Laken Riley Act, despite concerns regarding the bill's actual provisions.
Experts argue that there is confusion about the legislation, which is designed to detain illegal immigrants charged with crimes, but does not change existing deportation or detention policies.
The bill, introduced following the murder of nursing student Laken Riley, has sparked debates over potential risks of racial profiling and state-level overreach.
Notably, the bill allows state attorneys general to sue for enforcement issues, a move critics warn might upset the federal immigration system.
The Senate passed the bill 84-9, and it is set for further debate and voting next week.
