giuliani has links to the two key people in this investigation -- the fired fbi director james comey. he worked under giuliani in the southern district. and special counsel robert mueller was, you'll recall, director of the fbi during and after 9/11 when giuliani was new york mayor. the giuliani hire comes as the president has escalated his attacks on mueller. tonight giuliani told "the washington post," quote, i hope we can negotiate an end to this for the good of the country and because i have high regard for the president and for bob mueller. giuliani did not say whether a final decision has been made on a potential trump/mueller sitdown interview. that may be determined by the strength of giuliani's personal connection to trump. giuliani spent a lot of time on the campaign trail with the president and was a tireless surrogate for the president. his remarks about trump during the republican national convention may encapsulate their relationship. >> i am sick and tired of the defamation of donald trump by
