The problem with this agenda is that there is little evidence that Mr. Trump did commit crimes as president. A conviction is all but impossible.
The most plausible charge is that Mr. Trump obstructed justice by interfering with, and possibly lying to, Robert Mueller. Critics also argue that Mr. Trump may have broken the law by threatening to withhold military aid to Ukraine unless the Ukrainian government announced the opening of an investigation into the Bidens.
All of these charges would face formidable difficulties in court. No former president has ever been prosecuted for crimes committed during his tenure. Courts tread cautiously when new legal ground is broken, worried about upsetting reasonable expectations about what the law is. And judges interpret criminal laws strictly because the defendant’s freedom is at stake. Just a thought.
