WASHINGTON - Former CIA Director John Brennan says he warned Russia against meddling in the presidential election during a call to the head of the Russian intelligence service on Aug. 4.

Brennan told the House intelligence committee on Tuesday that he was the first U.S. official to call out the Russians for their activities. Brennan says he told the head of the FSB that if Russia continued to interfere, it would backfire and prevent any warming of relations.

He says the Russian intelligence official denied that Russia was meddling, but said he would raise the issue with Russian President Vladimir Putin.
