U.S. Sen. Elizabeth Dole is challenging her husband on the Final Four.

The Salisbury Republican and her husband, former Sen. Bob Dole, have agreed to a wager on the NCAA tournament game Saturday between UNC-Chapel Hill and the University of Kansas.

The loser of the bet will donate $1,000 to the academic scholarship fund of the winning team's school as well as assume dog walking duties for the couple's miniature schnauzer, Leader.

"One North Carolina team already had Kansas on the ropes, and now it's time for the Tar Heels to finish the Jayhawks off," said Elizabeth Dole in a statement.
