Apparently, Texas has filed a suit against GA, MI, PA, and WI at the Supreme Court [View all]

[Goodheart]

alleging that those states violated the Constitution because, allegedly, those states made changes to voting regulations through courts rather than through the state legislatures, and because differences in voting rules in different counties violated, allegedly, the Constitution’s Equal Protection Clause.

Funny thing... I can't find reference to the suit except on right wing sites, although I'm pretty sure it was actually filed.
