senate judiciary board on january 3rd, trump tried to pressure rosen to overturn the election for hours. what role will he play in this investigation? i'm talking about rosen. >> key witness. that is the role that he will play. listen, i can tell you, don, i have been there many times. i've sat in the chair that he sat in today for eight, ten, 12 hours at a stretch. it is a long and hard day. mr. rosen is making himself available. administration has not blocked his appearance with any claims of executive privilege and all indications are he's providing a lot of detailed information to the committee. that is going to be key in not just expanding their um understanding of what happened but driving future subpoena requests. this will enable them to target other significant witnesses who people they want to call in front of the committee. >> always a pleasure. thank you, sir. >> thanks, don. is our democracy heading towards extinction? i'm going to speak with a guy
