(WASHINGTON) — Former New York City Mayor Rudy Giuliani is joining the legal team defending President Donald Trump in the special counsel’s Russia investigation, a Trump attorney said Thursday. With the addition of Giuliani, Trump gains an experienced litigator and former U.S. attorney in Manhattan. Trump is looking to bring his involvement with special counsel Robert Mueller’s investigation to a close, and is considering whether to sit for questioning by Mueller’s team. Giuliani also fills the void left by attorney John Dowd, who resigned from the legal team last month. Trump personal attorney Jay Sekulow told The Associated Press that Giuliani will be focusing on the Mueller investigation — not the legal matters raised by the ongoing investigation into Trump attorney Michael Cohen.
