A prosecutor told a jury at the start of a fraud trial Monday that a Brooklyn preacher exaggerated his ties to New York City Mayor Eric Adams and let greed overtake him as he looted a parishioner’s retirement savings and tried to extort a businessman to fuel his lavish lifestyle. Lamor Miller-Whitehead, 47, a Rolls Royce-driving bishop, was accused by Assistant U.S. Attorney Jessica Greenwood of telling the owner of an auto repair shop that he could get the mayor to “do official favors” if he and the businessman teamed up on real estate deals that could earn them millions of dollars. Miller-Whitehead has pleaded not guilty to wire fraud, attempted extortion and making false statements to federal law enforcement officials.
