for a sitdown interview with the president. they are okay with the prospect of an interview, but they're saying any questions about obstruction of justice should be limited in scope, and perhaps only answered on paper. meanwhile, mueller's team not at all interested in that. they have basically said they want to ask the president about collusion, about obstruction of justice and about his associates' contacts with russians. but the question about whether or not the president answers obstruction questions from mueller is all about the prospect of what guiliani is calling a perjury trap. now, listen to him explain what he's worried about in the context of a perjury trap on hannity last night. >> the reality is, he doesn't need to ask a single question on obstruction. he has all of the answers. they're not going to change. the president is not going to change his testimony. so stop the nonsense. you are trying to trap him into perjury, because you don't have a a case.
