According to the Daily Beast, a source familiar with the situation says President Donald Trump's Justice Department is planning to take another look at Hillary Clinton's use of a private server during her stint as Secretary of State in hopes of acquiring new insight as to how classified information was handled.
Officials’ questions include how much classified information was sent over Clinton’s server; who put that information into an unclassified environment, and how; and which investigators knew about these matters and when. The Sessions ally also said officials have questions about immunity agreements that Clinton aides may have made.
Trump has demanded that Clinton's emails be re-investigated on multiple occasions, most recently calling for Clinton aide Huma Abedin to be jailed, making the appearance of a non-political investigation difficult for the DOJ to accomplish.
“I think that even that is extremely dangerous, and that the Justice Department should not be opening itself up to the perception that it is bending to political pressures from the White House,” [said Brian Fallon, formerly a spokesperson for the Justice Department and Clinton’s presidential campaign]. “The Justice Department is supposed to operate independently of the White House, and even if this is just a perfunctory step that they’re taking to try to appease the president, that in and of itself is an abuse of the DOJ authority.”
At a debate during the 2016 presidential election, Trump threatened Clinton with jail in a particularly noteworthy exchange:
“If I win, I am going to instruct my attorney general to get a special prosecutor to look into your situation,” he said, referring to her emails, “because there has never been so many lies, so much deception.”
“It’s just awfully good that someone with the temperament of Donald Trump is not in charge of the law in our country,” she replied.
"Because you’d be in jail,” he retorted.
