One of the trickiest challenges for incoming President Joe Biden is what do to about his predecessor, Donald Trump: investigate him for possible crimes, or leave him alone?
There’s a case for each route. Investigating whether Trump violated election law, obstructed justice during the Robert Mueller probe, or committed campaign-finance felonies would show no president is above the law and possibly deter future presidents from abusing their power. But it could interfere with Biden’s policy agenda while also making it look like Biden is using federal power to hurt a political rival.
Letting Trump off the hook might calm the political warfare that exploded on Jan. 6 with the riots at the U.S. Capitol. But if Trump committed crimes without consequence or even scrutiny, it would invite other presidents to do the same.
