Sean Duffy may withhold $73 million in highway funds from New York, citing improper issuance of commercial driver's licenses to immigrants that remain valid long after their legal authorization to be in the country has expired.Federal investigations revealed over half of 200 reviewed licenses were issued incorrectly, prompting Duffy to demand New York revoke flawed licenses and fix the system within 30 days, a call that Governor Kathy Hochul was urged to address despite state official Walter McClure defending current practices.
