Famed lawyer Alan Dershowitz said Tuesday the questions special counsel Robert Mueller wants to ask President Trump may place added pressure on Deputy Attorney General Rod Rosenstein to recuse himself from overseeing the Russia probe.

“The emphasis in the questions on why the president fired [FBI Director James] Comey strengthens the case for Rod Rosenstein recusing himself, because there’s absolutely no doubt that he will be called as a witness if there is an indictment,” Dershowitz said on CNN.
