Richard Painter is emerging as one of my favorite pundits seen regularly when questions arise about the Trump administration.

Painter served as ethics lawyer/watchdog for President George W. Bush. Thus, he — more than likely — is a loyal Republican. He also is no fan of Donald John Trump Sr., which likely is why I appreciate his commentary so much.

Painter now teaches law at the University of Minnesota.

He recently commented on a statement from Trump senior adviser Kellyanne Conway, who suggested that the administration might administer lie-detector tests to aides in the hunt to determine who’s leaking information to the media.

Painter’s response via Twitter? “Kellyanne wants lie detectors in the White House? Try one on the press secretary podium. The place will light up like a disco!”

Press secretary Sarah Huckabee Sanders has pledged never to lie from the White House press podium. I would like very much to give her the benefit of the doubt.

However, maybe Sanders ought to follow Professor Painter’s suggestion: hook up to the polygraph machine — just to be sure.
