Petraeus calls for immediate sanctions on Russia over alleged intelligence support to Iran

Retired four-star Gen. David Petraeus is calling for immediate sanctions against Russia after reports that Moscow is providing Iran with intelligence support — assistance he says could explain the improved accuracy of Iranian missile and drone attacks.

"[President Trump] should ask Congress to pass the sanctions bill that is in the Senate…" Petraeus told "The Sunday Briefing." 

"[Sen. Lindsey Graham] has over 90 out of 100 senators supporting it. It would be a very powerful signal to Russia.
