The Trump administration’s pick to oversee a conspiracy investigation into the president’s foes has resigned under pressure from the Justice Department.

Joe diGenova stepped down from his role overseeing DOJ’s vast so-called conspiracy investigation amid disagreements with top Justice Department officials over the pace of the south Florida-based probe that was intended to pursue possible charges against a swath of Donald Trump’s top political foes, according to people briefed on the matter.

DiGenova’s resignation came after a series of clashes with top Justice officials, including one in recent days with someone who advised him he had lost the confidence of his superiors, one of the people briefed on the discussions said.
