Sen. Bob Corker says he believes Russia tried to interfere in the U.S. presidential election — but international spying happens all the time.

The Senate Foreign Relations Committee chairman told MSNBC on Tuesday that he has “no proof” of Russia’s involvement and said foreign political organizations and governments secretly snatch information from each other all the time.

Corker says “what was unprecedented was the overt nature” of the interference ahead of the Nov. 8 election. He says “it was done in a manner to be visible to the world. That was a new step.”

He says “it was done to try to embarrass and discredit” the winner, who was expected to be Democrat Hillary Clinton.

Democratic National Committee emails were released by WikiLeaks, leading to a number of embarrassing disclosures about some Clinton confidents.

Republican Donald Trump instead shocked the world with his victory.
