Treasury Secretary Steven Mnuchin, when asked about Rubio’s comments on ABC News’ “This Week” today, defended the idea of a joint Russian-U.S. cyber security unit, calling it “a very significant accomplishment.”

“Well, in all due respect, and I think very highly of the senator, but let me just comment on that. I think this is a very important step forward that what we want to make sure is that we coordinate with Russia, that we’re focused on cybersecurity together, that we make sure that they never interfere in any democratic elections or conduct any cybersecurity,” he said.
