Former Republican presidential candidate Rick Santorum is canceling a trip to Iowa trip after being hospitalized over the weekend.

Virginia Davis, spokesperson for Santorum’s Patriot Voices, said Sunday that former Pennsylvania Sen. Santorum became sick while in South Carolina on Saturday and was admitted to the hospital for a “gastro-intestinal illness and dehydration.”

“He is feeling better today but remains in the hospital and is unable to travel to Iowa on Monday, April 15 for previously scheduled events,” Davis said. “He is expected to resume a full schedule later this week and looks forward to returning to Iowa soon.”

Santorum, who won the Iowa caucuses in 2012, was scheduled to attend a luncheon in Des Moines at the John Paul II Medical Research Institute.

He was also scheduled to give the keynote address at the 13th Annual Spring Kick Off of the Iowa Faith & Freedom Coalition in Urbandale.

Since the election, Santorum has said he’s open to another run for president in 2016.
