Rep. Jamie Raskin offers update on cancer treatment

Rep. Jamie Raskin is battling diffuse large B cell lymphoma. He offered an update on his treatment.

"I am hanging tough. My energy is good. I'm losing about 40 or 50 hairs a day, I would think, to chemo, so that's upsetting. But otherwise I'm hanging tough. And the doctors are very optimistic and I'm very optimistic that the Chemo is going to get the cancer,” said Raskin.
