The nation’s highest court this week heard arguments around whether to count mail-in ballots that arrive after Election Day. 

The case is called Watson v. RNC, the Republican National Committee. 

The state of New York counts mail-in ballots if they are postmarked by Election Day and received within 10 days of the election. But the high court’s conservative justices seemed skeptical of that practice.

Andrew Garber, a counsel on the Brennan Center’s Voting Rights and Elections Program team, discussed the case with Capital Tonight’s Susan Arbetter.
