(CNN) - Ohio Rep. Stephanie Tubbs Jones, a Democratic superdelegate and one of Hillary Clinton's most ardent supporters, was rushed to the hospital Tuesday evening and is currently in stable condition, her office confirmed to CNN Wednesday.
Spokeswoman Nicole Williams would not give out further details, though CNN affiliate WEWS reports police officers were called to Tubbs-Jones' car Tuesday night for an emergency. Williams would not say whether Tubbs Jones is currently conscious.
Elected to Congress in 1998, Tubbs Jones is the first black female U.S. Representative from Ohio. She was an early supporter of Clinton's White House bid but endorsed Barack Obama in June after the New York senator bowed out of the race.
