Mayor Eric Adams has appointed a former New York City police official and close confidant as a paid senior adviser – while allowing him to keep his job as an executive at the Resorts World New York City casino in Queens, according to city officials and a person close to Resorts World.

Since May 31, the adviser, Timothy Pearson, a retired police inspector, has served as both a city official and the vice president responsible for overseeing security at the casino, which is seeking state approval to expand its gambling offerings in Queens. City support for its bid could prove pivotal.

On top of what he earns from the casino job, Mr. Pearson receives a city-funded salary through the nonprofit New York City Economic Development Corporation.
