HARI SREENIVASAN:

Russian interference in the 2016 U.S. presidential election is currently the subject of several investigations. But is Russia still mounting operations in the United States?

According to former CIA Deputy Director Michael Morell and former Congressman Mike Rogers, the answer is yes. They write in a Washington Post op-ed that Russia's information operations in the United States continued after the election, and they continue to this day.

We get two perspectives on this.

Laura Rosenberger directs the Alliance for Securing Democracy, a program of the German Marshall Fund that tracks Russian influence operations. A foreign policy adviser to the most recent Hillary Clinton presidential campaign, Laura also served in the State Department during the George W. Bush and Barack Obama administrations.

John Sipher is a 28-year veteran of the CIA who was based in Moscow in the 1990s. He subsequently oversaw operations against Russian intelligence services. He's now with the consulting firm CrossLead.

Laura, let me start with you.
