As far as I can tell, that is a Ross Perot quote. Multiple books quote him saying things like that during the 1992 campaign and that is supposedly the standard he applied to executives at EDS and said he would apply in his administration. I'm not sure if he was also referring to Clinton. A lot of people think this quote originated with Truman, but it's hard to figure out when Truman would have said this.
It was Perot’s saying.
Never heard anything like that during HST’s presidency.
