In May 2008, New York State Attorney General Andrew Cuomo announced that the MTA policy of giving free lifetime passes to current and former board members violated New York State law. The MTA board initially resisted changing this policy.
Mack was reappointed to the MTA board in 2019 as the representative for Nassau County. In 2022, the MTA took away placards from MTA board members which had allowed them to park anywhere in the city legally. This led Mack to throw a tantrum. After losing his placard, Mack began voting against MTA plans for congestion pricing in New York City, which had been in the works since 2019.
