As far as I know, the line of communication between the U.S. and Russia continues to be open and the battlefield commanders are able to communicate with one another. I am aware that there have been certain public statements made out of Moscow.

I would want to be fully informed before advising the president.

It's important that we keep our priorities straight. And we believe that the first priority is the defeat of ISIS. That by defeating ISIS and removing their caliphate from their control, we've now eliminated at least or minimized a particular threat not just to the United States, but to the whole stability in the region.

I think the relationship between the USA and Russia is too important. And it's too important to not find a way to move forward.

The military progress both in Syria and in Iraq has been remarkable since President Donald Trump's inauguration. We have continued to liberate areas. We are making tremendous progress in liberating Mosul in Iraq, working with coalition forces, we're moving to position to liberate Raqqa.

We are making tremendous progress that ISIS really does present to the homeland and to other homelands of allies around the world.
