On day three of the Judiciary Committee’s confirmation hearings for Supreme Court justice nominee Brett Kavanaugh, Sen. Cory Booker, D-New Jersey, threatened to release secret emails, even if it meant being expelled from the Senate.

He is one of three Senate Democrats on the committee, including California’s Kamala Harris and Minnesota’s Amy Klobuchar, said to be contemplating a presidential run in 2020 — and there’s nothing like a nationally televised hearing to grab attention and amass footage for future campaign commercials.
