“The President urged me, like he has everyone in the administration, to fully cooperate with the special counsel. I was happy to voluntarily sit down with them,” Sanders said in response to a question from CNN.

The interview is one of the final known interviews by Mueller’s team. It came around the same time as the special counsel interviewed former White House chief of staff John Kelly, well after a number of other senior officials, including former White House communications director Hope Hicks and former press secretary Sean Spicer, were brought in for questioning.
