The Justice Department has opened an investigation into Sen. Ruben Gallego regarding possible campaign finance violations, prompted by a whistleblower complaint and focusing on the use of campaign funds and a leadership PAC for family travel and child-care expenses since 2019. Federal Election Commission records document reimbursements for trips to Puerto Rico, Nantucket, Miami, Chicago, Disneyland, and Disney World, along with over $18,000 in child-care payments. Gallego has stated that such practices are routine and permitted by FEC rules.
