Rep. Trey Gowdy, who was involved in the drafting of the controversial FISA memo, told CBS’ “Face the Nation” it has no effect on the Russia investigation:

There is a Russia investigation without a dossier… the dossier has nothing to do with the meeting at Trump Tower. The dossier has nothing to do with an email sent by Cambridge Analytica. The dossier really has nothing to do with George Papadopoulos' meeting in Great Britain. It also doesn't have anything to do with obstruction of justice.

Why it matters: President Trump claims the memo "totally vindicates" him and has suggested it should bring an end to the Russia "witch hunt." Gowdy disagrees.

Gowdy did defend the decision to release the memo, arguing the use of the Steele dossier to obtain a FISA warrant against Carter Page was “unprecedented” and inappropriate.
