Attorneys general in Missouri and Kentucky have joined a Republican lawsuit challenging Pennsylvania mail-in ballots before the U.S. Supreme Court, according to multiple reports.
A spokesperson for Missouri Attorney General Eric Schmitt was cited by the St. Louis Post-Dispatch as saying that Schmitt intends to add his name to an amicus brief—a legal document that can be filed by a non-party in a given case—in a lawsuit brought by the Pennsylvania Republican Party challenging the state’s Supreme Court decision to extend by three days the deadline for receiving mail-in ballots, provided they are postmarked by Election Day.
