During his appearance on "Fox & Friends," Schweizer alleged that Clinton campaign chair John Podesta probably violated federal law when he failed to disclose his stock holdings in a Kremlin-funded company.

"In 2011, John Podesta joins the board of this very small energy company called Joule Energy based out of Massachusetts," Schweizer said. "About two months after he joins the board, a Russian entity called Rusnano puts a billion rubles -- which is about 35 million dollars -- into John Podesta's company. Now, what is Rusnano? Rusnano is not a private company, Steve. It is a fund directly funded by the Kremlin. In fact, the Russian science minister called Rusnano Putin's child. So you have the Russian government investing in one of John Podesta's businesses in 2011, while he is an advisor to Hillary Clinton at the State Department."
