When asked on Thursday how he would assess the whole government response to Russian threats during a Senate Armed Services Committee hearing, Gen.

President Donald Trump has only glancingly and grudgingly acknowledged the consensus view of US intelligence agencies that Russia meddled in the 2016 presidential campaign with a view to helping him get elected.
