Democratic senators Dick Durbin and Alex Padilla introduced the 'Immigration Warrant Reform Act' to limit warrantless ICE arrests and indefinite detention. The bill would require an administrative warrant with probable cause, a bond hearing within 24 hours of warrantless arrests, and custody reviews every 60 days by a judge. The senators cited reports of US citizens and legal immigrants being wrongly detained during operations like the Chicago 'Operation Midway Blitz,' though advocates warn the bill still gives ICE broad discretion.
