Presumptive Democratic presidential nominee Joe Biden told\u0026nbsp;NPR on Thursday that while he was unsure if it was \u0022good for democracy,\u0022 if elected he would not stand in the way of a hypothetical Justice Department prosecution of President Donald Trump for crimes committed in office.\u0022Look, the Justice Department is not the president\u0026#039;s private law firm,\u0022 the former vice president\u0026nbsp;said. \u0022The attorney general is not the president\u0026#039;s private lawyer. I will not interfere with the Justice Department\u0026#039;s judgment of whether or not they think they should pursue the prosecution of anyone that they think has violated the law.\u0022Joe Biden said he believes prosecuting a former president would be a \u0022very unusual thing and probably not very ... good for democracy,\u0022 but he wouldn\u0026#039;t stand in the way of a future Justice Department pursuing criminal charges against President Trump. https://t.co/1XrvJQwkub— NPR Politics (@nprpolitics) August 6, 2020The comments came in response to a question from\u0026nbsp;NPR\u0026#039;s Lulu Garcia-Navarro on remarks made last year by Sen. Kamala Harris (D-Calif.), a frontrunner for Biden\u0026#039;s pick for vice president, that the Justice Department would have \u0022no choice but to investigate Trump after his presidency.\u0022According to NPR:Trump has been connected with alleged illegal activity by his former lawyer and fixer Michael Cohen\u0026nbsp;and investigators working for former special counsel Robert Mueller.\u0026nbsp;What isn\u0026#039;t clear is whether federal authorities are investigating the president or whether prosecutors might take action against Trump if he no longer enjoyed the privileges that protect him from being indicted as a sitting president.Biden declared the idea of prosecuting a former president \u0022very unusual\u0022 and said he would not weigh in on the decision and rather allow federal law enforcement officials to come to their own conclusions.\u0026nbsp;\u0022In terms of saying, \u0026#039;I think the president violated the law. I think the president did this, therefore, go on and prosecute him\u0026#039;—I will not do that,\u0022 Biden said.Progressives have expressed concern that Biden could follow the lead of his former boss President Barack Obama, who said that the country should \u0022look forward, not back\u0022 when it came to his predecessor, former President George W. Bush.
