Democrat Joe Biden defeated US President Donald Trump in Arizona, Edison Research projected on Thursday, increasing his margin of victory over the Republican incumbent by 11 Electoral College votes following the Nov. 3 presidential election.
Trump has yet to concede five days after Edison Research and major media outlets said Biden had surpassed the 270 Electoral College votes needed to capture the presidency.
