so, why do you think the public impact could be when people hear these witnesses testify and say things in their own words? >> i think there's a lot of strength that will come from looking at these professionals, these people who in many cases have devoted their entire lives to protecting this country. i think about lieutenant colonel vindman, for example, who suffered battle wounds. to hear them say with their own words their observations of the behavior of this president i think will be really compelling. and i do think we have a responsibility to hold these public hearings, because while public sentiment is everything, as lincoln said, he also said that those who are able to shape public sentiment can achieve amazing things. we have a responsibility to help shape the public view of this by having these facts come forward and have them be able to see and hear from those witnesses and tell their own interpretation, their own story.
