showdown between trump and mueller. we are all so excited that you're in the building. it's great to have you here. >> you're so nice to have me. thanks. >> let me ask you about rudy's latest move. >> so the only person who was surprised by the fact that bob mueller didn't want to submit a written take home test to the president was rudy giuliani. no one really expected this was how it would play out, not because mueller is being difficult, not because he wants to put the president in a perjury trial, but because as a serious prosecutor, you have obligations to build the evidence in the case. this an instance where mueller apparently feels strongly he needs an in-person interview and the law will likely support that. >> there's plenty of evidence. the things that are written for him have no relationship to the things in his own brain. he reads a speech and within 45 minutes he attacks it on twitter. there's no example you can point to where anything that's been written for him by anyone else
