Treasury Secretary vs. Treasury Secretary

New York Times: “Raising eyebrows in economic circles, Lawrence Summers, the mercurial Treasury secretary for President Bill Clinton, has leveled a barrage of increasingly personal criticism at the current Treasury secretary, Steven Mnuchin. In podcasts, blog posts, op-eds and on Twitter, Mr. Summers… has accused Mr. Mnuchin of damaging the credibility of Treasury by making ‘irresponsible’ economic assessments of the administration’s tax plan and acting as a ‘sycophant’ to President Trump. The attacks have alternately amused and angered those who run in economic circles, with some saying it is Mr. Summers who is damaging the credibility of the office by leveling public attacks on a sitting Treasury secretary.”
