JOHNSTON — The U.S. attorney general received a less-than-glowing job performance appraisal from one of his predecessors Friday in Iowa. Eric Holder, the former attorney general during Democratic President Barack Obama’s tenure, said he is “extremely disappointed” in Attorney General William Barr, the second to serve during Republican President Donald Trump’s tenure. Holder gave his assessment of Barr on Friday during the filming of an episode of “Iowa Press” on Iowa Public Television. “I’m both surprised and extremely disappointed,” Holder said when asked to assess Barr’s performance since taking the job in February. “I actually thought that he was an institutionalist, and I thought that he would actually be at odds with President Trump relatively soon in his tenure, and he has proved to be anything but that.” Barr has been criticized for his framing of the special counsel’s report on Russian meddling in the 2016 presidential election.
