the committee would like to know more about. and of course they are sending subpoenas. i must say, john, i'm not very hopeful that's going to change any of the dynamics of this. nixon totally stonewalled all of the subpoena requests. yes, it was added as an article of impeachment. he didn't care. in fact, that was the weakest article that was voted against him by the committee, 21-17. didn't even carry all the democrats. so i think they're not particularly worried about their stonewalling strategy. >> very important context. we're going to pick this up after the break. we've also got reaction tonight, sharp reaction from former vice president joe biden. and later, some inklings of reaction from the gop but also a fair amount of avoidance. that and more as our "360" coverage continues. we used to love going out with julia and mike, but since they bought their new house... which menu am i looking at here? start with "ta-paz." -oh, it's tapas. -tapas. get out of town. it's like eating dinner with your parents.
