President Donald Trump’s own recent words and actions could end up undermining any criminal cases that he has encouraged against several of his political foes, some legal experts say. The pushing out of a U.S. attorney could also bolster arguments that any criminal charges should be thrown out, some legal experts say. “It’s all out in the open.”Prosecutions against Schiff, James or Comey could also test the government’s reputation for bringing good faith prosecutions, depending on the strength of the evidence, legal experts say. Grand juries could push back on flimsy cases and decline to indict, or judges could take a closer look at claims of selective prosecution. Selective prosecution does apply to the bringing of criminal charges in the first instance, Barr said, but meeting all the elements is “very difficult, almost impossible, and it’s only happened very rarely.”
