(Video) In Interview, Trey Gowdy Effectively Demolishes Nunes Memo

In less than a minute, Trey Gowdy takes the Nunes memo apart. His Republican colleagues will not be happy.

Numerous Republicans, including President Donald Trump, have pointed to the now-public Nunes memo as proof that the Russia investigation is the hoax they have always claimed. The president tweeted on Saturday that he has been vindicated in the "Russian Witch Hunt".

But Rep. Trey Gowdy (R-SC) disagrees and said as much on CBS News' Face the Nation.

CBS News White House and senior foreign affairs correspondent Margaret Brennan asked: "The memo has no impact on the Russia probe?"

"Not to me, it doesn't — and I was pretty integrally involved in the drafting of it," Gowdy, a former federal prosecutor, said. "There is a Russia investigation without a dossier. So to the extent the memo deals with the dossier and the FISA process, 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. So there's going to be a Russia probe, even without a dossier."

While some Republican officials and conservative media outlets have hinted that Trump could use the memo as reason to fire Deputy Attorney General Rod Rosenstein, others have openly stated that the memo provides no such cause:

[K]ey Republicans, including House Speaker Paul Ryan, R-Wis., have echoed Gowdy's reassurances. Ryan said this week that the memo "does not impugn the Mueller investigation or the deputy attorney general."
