Forty years is long enough: that’s what Congressman Henry Waxman (D-Ca.) said when he announced his plans to retire at the end of this year. But the veteran lawmaker says he’s not leaving the Hill because he’s fed up with congressional gridlock. On the contrary, Waxman says he still believes the legislative branch can be a powerful force for good. And his supporters say he’s had a strong hand in that force for good: Congressman Waxman wrote some of the most influential pieces of legislation, including The Clean Air Act and The Affordable Care Act. Rep. Henry Waxman joins Diane in the studio to talk about his long career in Congress and the challenges ahead.
