When President Donald Trump’s campaign decided to challenge Gov. Phil Murphy over New Jersey’s plans for a mail-in general election, its local counsel for the case is an attorney who is not quite a household name. But Michael Testa Jr. has rapidly become one of Trump’s key allies in New Jersey.

Tuesday’s suit claims the mail-in election plan is fraught with risk and that the state is ill-equipped to prevent voter fraud. The Trump campaign and the Republican National Committee are represented by Consovoy McCarthy of Arlington, Virginia, which focuses on election law, along with Testa, of Vineland, New Jersey’s Testa Heck Testa & White.
