Washington (CNN) South Carolina Republican Rep. Trey Gowdy said the recently released, controversial GOP memo alleging FBI abuses of its surveillance authority does not have "any impact on the Russia probe," and even without the Steele dossier, there would be a Russia investigation.

"There is a Russia investigation without a dossier," Gowdy said in an interview that aired Sunday on CBS's "Face the Nation," days after he announced his decision not to seek re-election.

President Donald Trump authorized the release of the memo from the House Intelligence Committee on Friday, and has since claimed it "totally vindicates" him in the ongoing investigation around allegations of possible coordination between his associates and Russia to influence the 2016 election.

Gowdy, however, said he believes the memo does not affect the Russia investigation and has no connection to key storylines about the matter.

"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," Gowdy said. "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."
