One of Dick Cheney's daughters says the hospitalized former vice president could go home on Monday after receiving medication to treat a fluid buildup related to his aggressive form of heart disease.

The 69-year-old, who has had five heart attacks, was admitted to

George Washington University Hospital on Friday after experiencing discomfort. His last heart attack—described as a mild one—was in February.

Liz Cheney tells "Fox News Sunday" that her father is feeling better and hopes to be released on Monday.

Cheney's office says Cheney has received intravenous medication and that he's "markedly improved."
