Why it matters: The $510,000 in spending by two PACs associated with the International Union of Police Associations is the largest independent political expenditure of the 2022 cycle to date. It appears geared less toward unseating any of the members and more toward raising money for the groups themselves. What's happening: Both groups — Law Enforcement for a Safer America PAC and Honoring American Law Enforcement PAC — are affiliated with the International Union of Police Associations. The Florida-based IUPA represents about 20,000 law enforcement professionals. Together, the two PACs reported spending $127,500 attacking each of the four House Democrats in the progressive "Squad": Reps. Alexandria Ocasio-Cortez of New York, Ilhan Omar of Minnesota, Ayanna Pressley of Massachusetts and Rashida Tlaib of Michigan.
