A Delaware lawmaker who came under fire last year for using a racist and sexist slur to refer to sex workers was arrested on shoplifting charges Tuesday, just days after announcing that he was resigning for health reasons. Newark police said a warrant was issued Tuesday for Rep. Gerald Brady’s arrest on two counts of shoplifting, and that Brady, 65, turned himself in a few hours later. House Democrats announced last Friday that Brady was resigning effective Feb. 4, but they did not disclose that he was under criminal investigation.
