Trump’s Justice Department has targeted some of his foes, including Federal Reserve Governor Lisa Cook and Democratic U.S. Senator Adam Schiff, over alleged fraud on mortgage documents, a crime a Reuters review showed that the federal government rarely prosecutes. Federal prosecutors in Virginia are also investigating Comey over the FBI’s probe into Trump’s 2016 presidential campaign. Former federal prosecutors called Trump’s decision to oust a U.S. Attorney for failing to indict his enemies disturbing. “This is an extremely dangerous development,” said Randall Eliason, a former federal prosecutor who now teaches law at George Washington University.
