The rebuttal focuses on four key points having to do with the legal underpinnings of the GOP-produced document:

That Nunes’ memo fails to demonstrate that the government lacked enough evidence beyond a dossier from former British spy Christopher Steele to obtain a FISA warrant on Page.

That Steele’s expertise on Russia and organized crime would have outweighed any concerns a FISA court would have had about the funding of Steele’s work by partisan actors — funding sources that Steele may not have even known about.

That Nunes’ memo “provides no credible basis whatsoever” for removing Deputy Attorney General Rod Rosenstein, who oversees the investigation led by special counsel Robert Mueller.

That Nunes’ memo shows that Republicans “are now part and parcel to an organized effort to obstruct” Mueller’s probe.
