President Trump’s former campaign chairman on Monday denied any ties to or contact with the Russian government after the FBI confirmed it is investigating Trump allies’ alleged links to Moscow.

Paul Manafort said he “had no involvement” in Russia’s intervention in the 2016 presidential elections, including its email hacking of prominent Democratic groups and figures, and never spoke to Russian officials who claimed to be involved.

“The suggestion that I ever worked in concert with anyone to release hacked emails or sought to undermine the interests of the United States is false,” he said in a statement.
