As Donald Trump was in Washington on Friday to promote his new Pennsylvania Avenue hotel, concerns continued to grow a few blocks away on Capitol Hill about Russia undermining the U.S. election.

Sen. Dianne Feinstein, the ranking Democrat on the Intelligence Committee, said she was talking to her House counterpart, fellow Californian Adam B. Schiff, about what could be done regarding the threat.

“I think Russia ought to understand the ramifications of this, and the animus that’s created by it. This is our electoral process. The United States of America runs our election. Russia does not,” Feinstein said. “Nor do we interfere in Russian elections. And to have this tradition, this practice, this legal situation really decimated by hackers is something that is not acceptable.”

Feinstein told reporters that there was a “reasonable certainty” of Russian attempts to influence the 2016 presidential contest.

“So I hope, at the highest level, Russia will understand this, and Putin will give the direction to cease and desist,” she said.
