The U.S. Supreme Court on Monday threw out what is likely the last legal challenge remaining about the choice of Arizona voters of Joe Biden for president.

The Arizona Senate’s Republican whip attempted to pressure a woman who went dumpster-diving for ballots into handing documents she found over to him instead of law enforcement and implied both of them could be killed for trying to expose fraud.

The 11 electors pledged to Joe Biden are set to cast their votes today even as yet another court hearing is set in a bid to invalidate what they are doing and lawmakers look to see how the election was conducted.
