The Supreme Court has agreed to consider reviving a Republican challenge to an Illinois law that allows mail ballots to be counted if they are received up to two weeks after Election Day.

U.S. Rep. Mike Bost, R-Muphysboro, and two Illinois delegates to the Republican National Convention first filed the lawsuit against the Illinois State Board of Elections in May 2022 — alleging that counting ballots after the election violated federal election law.

The justices added four cases to their docket for next term, including a lawsuit brought by a conservative group challenging an Illinois law that allows mail ballots to be counted after Election Day.
