On July 25th, Attorney General William Barr directed the federal Bureau of Prisons to reinstate the death penalty. The next day, former White House counsel and witness in Nixon's impeachment trial John Dean posted a tweet critical of Barr. He wrote that Barr must be an "Old Testament kind of guy" to do such a thing.
Like presidential hopeful Mayor Pete Buttigieg's habit of calling Mike Pence a "Pharisee," Dean's reference implies that the central scripture of Judaism is the source of bad things. (In response to feedback, Buttigieg stopped using the term Pharisee and began to use the word "hypocrite" to describe Pence.)
