Former U.S. Sen. Kay Hagan, a Democrat who represented North Carolina, has been hospitalized after falling seriously ill, her family said.

Hagan's brother told The Lakeland Ledger in Florida Hagan was rushed to a Washington, D.C., hospital Thursday and was being treated in an intensive care unit.

Joe Ruthven of Lakeland said Hagan didn't have a heart attack and isn't in a coma. He wouldn't give any further details.

Hagan, 63, was elected in 2008 and served one term before she was defeated by Republican Thom Tillis. A spokeswoman said she formerly lived in Lakeland but currently resides in Greensboro, North Carolina.

The Hagan family said in a statement released to The Associated Press that "Kay is receiving the best possible medical care." It didn't give further details and asked for privacy.

Tillis sent a statement on his Twitter account wishing for Hagan "a speedy recovery back to good health."
