20-minute speech, you get to see the president, senator sessions and ben carson. the president for awhile looked like he was texting, then he looked tired. >>steve: a little squirmish. >>gretchen: some people criticized dr. ben carson. was this the right forum and as a physician what did he know about taxes? he responded to that question as well. >> why did you take it upon yourself to go beyond medical policy and talk about tax policy? >> one of the things i also said during the speech is there will be some people who say you're a doctor, a neurosurgeon, you should be sticking to that. i mentioned the fact that five physicians signed the declaration of independence and were involved in the framing of the constitution and the bill of rights and several other things. there's absolutely no reason at all that physicians, scientists shouldn't be involved in things that affect all of us.
