Former Trump administration national security adviser Michael Flynn filed court papers Tuesday to withdraw his guilty plea, saying federal prosecutors had acted in “bad faith" and broken their end of the bargain when they sought prison time for him. The request came one week after the Justice Department changed its position on Flynn's punishment by recommending he serve up to six months behind bars for lying to the FBI during its investigation into ties between the Trump campaign and Russia. It was not immediately clear how the judge handling the case, Emmet Sullivan, would respond to the motion or whether he would actually permit Flynn to withdraw the plea — an extraordinary step that would presumably enable the government to bring additional charges if merited.
