Jessie Jackson Jr Selling House to Pay Medical Bills

Citing high healthcare costs Jessie Jackson is putting his modest 4 bedroom, $2.5 million home on the market.
“Like millions of Americans, Congressman Jackson and Mrs. Jackson are grappling with soaring healthcare costs and are selling their residence to help defray costs of their obligations,” said Rick Bryant, Jackson’s chief of staff. “The congressman would like to personally thank everyone who has offered prayers on behalf of his family.”
Are we to believe that congressional health insurance isn't good enough to sustain a congressman during a long illness? Something is wrong with this story. The senior Jackson own an Anheuser-Busch distributorship in Chicago and his son the congressman is going broke paying for rehab? He's giving up his seat? Hasn't he ever heard of Medicaid?
