Trump Keeps Calling for Investigations Into Democrats. Why That's Unusual

When Donald Trump was a presidential candidate, he'd often lead his crowds in chants of "lock her up," arguing that his opponent Hillary Clinton should go to jail. Now that he's president, his continued calls for Clinton and Democratic officials to be investigated take on a new, inappropriate heft.

Over the past 24 hours, Trump has said multiple times that the Justice Department should investigate Clinton and the Democratic Party.
