i want to bring in bob bear, call callan, legal analyst. paul let me start with you. the bottom line from what evan is reporting is that the fbi got a fisa warrant to wiretap a trump advisor, carter page, based on the explosive 32-page dossier. >> yes. >> ok. based on the dossier. did the fbi have to prove to anyone that anything in that dossier was true to get this warrant? >> yes, they have to convince a judge that they have probable cause to believe that the search that they're seeking to do air such veilance they're seeking to do will yield evidence of a crime. so whatever is in that dossier that they had to use had to per swede a federal judge that there's scat grounds here to conduct surveillance of an american sit zen. >> what that does, bob, does that open the page to the # 2-page dossier being true?
