Report: U.S. Investigating Flynn's Russia Calls

The U.S. is investigating calls between new national security advisor Michael Flynn and Russia's ambassador to the U.S., intelligence officials told CNN on Monday. Flynn conducted the calls in late December, including one on December 29, the same day the U.S. announced new sanctions against Russia and ordered 35 Russian diplomats out of the country. The investigation is reportedly part of a larger search into Russian activity, and used audio collected from "routine US eavesdropping targeting the Russian diplomats," CNN reported. The Trump administration has repeatedly denied any wrongdoing in the calls, denying any knowledge of or "even a basis for such an investigation."
