Trump earlier this month expressed frustration with a pair of his most loyal Cabinet members -- Attorney General William Barr and Secretary of State Mike Pompeo -- for what he described as a failure to implicate his political enemies in wrongdoing. More recently, Trump swiped at Treasury Secretary Steven Mnuchin, seemingly blaming him for not delivering a result after weeks of coronavirus relief talks with Speaker Nancy Pelosi. Trump’s public rebukes of his own Cabinet members have been remarkable though perhaps not entirely surprising; he has often criticized his health experts and has even jettisoned officials whose actions he dislikes.
