U.S. Sen. Dan Sullivan was "in good health" Thursday evening after an emergency appendectomy, according to a spokesman for the senator.

Sullivan, R-Alaska, was diagnosed with appendicitis early Thursday and underwent surgery that afternoon, Matt Shuckerow, the senator's deputy communications director, said in an emailed statement.

"He is in good health, but not available to comment on today's hearing at this time," Shuckerow said, referring to the Senate Judiciary Committee hearing on sexual assault allegations against Supreme Court nominee Brett Kavanaugh. Both Kavanaugh and Christine Blasey Ford, a woman who has accused Kavanaugh of sexual assault, testified at the marathon hearing.
