"Nobody in my administration got indicted," Obama added. "Which, by the way, is not that high a bar."

Trump has criticized Mueller's investigation as a partisan "witch hunt" and has called for it to be ended. He and allies have also pointed to text messages sent between a couple of FBI agents to suggest that the probe was politically motivated.

Obama has hammered the GOP on corruption in Washington and even employed the football team line before in a rally in Wisconsin two weeks ago. He repeated it again Sunday at a rally in Chicago and employed it twice last Friday.
