John Bolton has written in his upcoming book that Trump made explicit the quid pro quo that his lawyers are denying: that Trump told him directly that he wanted to keep the military aid frozen until the Ukrainian government agreed to help with investigations of Democrats. Not only that, but apparently the White House has had Bolton’s manuscript all month. Trump’s team knew this was coming.

…Nixon knew what was on the tapes, but until the Supreme Court ruled against him he might at least have hoped that he could keep them secret. Apparently in the Trump case, at least some people in the White House have known for weeks that Bolton was going to release this book, and yet they still encouraged their allies to say things that were about to be shown to be false.
