Steve Scalise tweets message 4 days after being shot

WASHINGTON -- The congressman grievously wounded when a gunman opened fire at a Republican baseball practice is delivering a Father's Day message through his Twitter account.

The message from congressman Steve Scalise of Louisiana on Sunday says: "Steve's greatest joy is being a father to Madison and Harrison, and a husband to Jennifer. This Father's Day has special meaning for the Scalise Family, and they send their best wishes to every family, especially the dads. Take the time to be close to the ones you love."

The message thanks the many people for their prayers, support and outpouring of love. It includes photos of Scalise and his family.

The House majority whip remains in serious condition at Medstar Washington Hospital Center. He has undergone several surgeries since Wednesday's shooting.

Scalise "continues to show signs of improvement" four days after being shot in the hip by a gunman in Alexandria, Virginia, doctors said Saturday.

In a statement released on behalf of the House majority whip's family, MedStar Washington Hospital Center said Scalise is now in serious condition. He had been in critical condition since arriving at the hospital in shock after the shooting.

The hospital said Scalise underwent another surgery Saturday to treat the gunshot wound. Doctors said Friday the bullet entered at his hip and traveled across his body, causing severe damage to internal organs. He suffered massive blood loss and was at "imminent risk of death" upon arriving at the hospital Wednesday.
