Ken Starr, the former independent counsel who investigated the Clinton presidency, said in a recent interview with Vice News that special counsel Robert Mueller’s probe would either end with an impeachment referral to Congress or an indictment once Trump is no longer president.

“Those are the two avenues that I see,” Starr said.

“My takeaway is there’s a very real prospect that on the day Donald Trump leaves office, the Justice Department may indict him. That he may be the first president in quite some time to face the real prospect of jail time,” California Rep. Adam Schiff, a former prosecutor and the incoming Democratic chairman of the House Intelligence Committee, added Sunday on CBS’s “Face the Nation.”

Concerned Trump might be able to outlast the threat of criminal charges under current law, Rep. Jerry Nadler, who in January will take over as chairman of the House Judiciary Committee, said he’s looking at passing legislation that would extend the statute of limitations to encompass crimes committed during Trump’s presidency.
