The basic premise of this prophecy is that the Democrats, and many others, will attempt to impeach President Donald Trump, but will fail to do so. And wow, is that ever true right now!
Edit (2020-02-05): As of today, with the full acquittal of DJT, this prophecy is considered fulfilled. However, that doesn't preclude this prophecy from being reactivated later should a second attempt to impeach him be put forward.
