nunez memo. a conclusion democrats reject. >> it's appalling. it's a misrepresentation. >> reporter: nunez soldiered on, this time threatening to impeach rod rosenstein, the man who oversees the mueller investigation for not providing enough records to congress. at the fundraiser nunez said impeachment should wait until after the senate confirms brett kavanagh to the supreme court. >> so i don't think you are going to get an argument from most of our colleagues. the question is the timing of it right before the election. >> reporter: as nunez has demanded more documents from rosenstein we have been told he has not read some of the key documents including one he is reading now which is the full copy of the application to surveill carter page. he wants that publically released but has not gone to the justice department to read it. >> my experts are back with me.
