President Donald Trump has placed a heavy shroud of silence over the executive branch. Likewise, no documents, no memos, no email or text-message exchanges will be made available to Congress as it considers impeachment. If you’re innocent, why would you keep all the copious evidence of your innocence locked away from Congress and the world? In a letter to Congress this week, White House lawyers did just that. Then, Trump says he also wants an investigation of Joe Biden, who is beating Trump by double-digits in most head-to-head polling.
