With Columbia Journalism Investigations and reporters from the USA TODAY NETWORK, New Yorker writer Jelani Cobb reports on allegations of voter disenfranchisement, how unfounded claims of extensive voter fraud entered the political mainstream, rhetoric, and realities around mail-in ballots, and how the pandemic could impact turnout.

Inside the no-holds-barred war for control of the Supreme Court. From Brett Kavanaugh to Robert Bork, this investigation explores how a 30-year-old grievance transformed the court and turned confirmations into bitter, partisan conflicts. The political struggle to control the country's highest court culminates in Amy Coney Barrett's nomination for Supreme Court Justice. This episode updates "Supreme Revenge," which premiered on May 21, 2019.
