As reports swirl that Donald Trump is considering multiple pardons before leaving office, speculation is that one of those pardons would be for Trump himself. Whether such a pardon would stand is up for debate.

Constitutional Law Professor Laurence Tribe tells MSNBC’s Lawrence O’Donnell that if Trump tried to pardon himself, it would not hold up in court: “If that were the case, then the president would not be below the law, he’d be above it.”

Tribe writes, “It’s time to end the uncertainty. Even a Trump-packed Supreme Court couldn’t disagree without reversing the American Revolution.”

Watch what else Tribe said above.
