this is not a fight we want to have. >> unfortunately, he picks a new onevery day. he lies about sothing different every day on twitter. these are unforced errors. this is like the balm sitting down in the tennis court like balmer. >> joining us is national security correspondent for "the new york times," david sanger. and former cia deputy director david s. cohen, the national security contributor for msnbc and nbc news. good to have you both on board this morning. everyone is focused on health care and the debate is there. but i got to ask both of you, how do we move forward from the president making the agencies elgs about the former president that he has done so over the weekend without walking it back and launching investigations. these allegations at this point clearly are not true. i'm not sure how they ever come to bear. how does this president have credibility around the world?
