Washington (CNN) Former Vice President Joe Biden is airing a new TV ad in Iowa that highlights his continued support for the Affordable Care Act, at a time when other progressive Democratic candidates are pushing for a "Medicare for All" approach.

The minute-long ad called "Personal" draws on his personal experiences after a 1972 car accident took the lives of his wife and daughter, and badly injured his sons Hunter and Beau, as well as his late son Beau's diagnosis with brain cancer.
