The latest is that Speaker Pelosi has threatened Trump with the appalling distinction of becoming the only president to be impeached twice unless he immediately resigns. And making matters worse (for Trump) is that the impeachment may not be a purely symbolic act. It is possible that Trump could be impeached and tried even after leaving office. It has actually happened before. In 1876 William Belknap, President Grant's Secretary of War was impeached and tried AFTER he had resigned for corruption.
