The number one topic and tag trending on Twitter: #ImpeachTrump

How about that. Calls to unseat Donald Trump from the office of the Presidency began to catch wind after he doubled down on his rebuke of violent protesters "on many sides" of the Charlottesville rally, and defended those who showed up to defend the preservation of the Confederate statue of Gen. Robert E. Lee.

By Tuesday evening the hashtag #ImpeachTrump had trended to the top of Twitter within 24 hours of former President Barack Obama's quoting of Nelson Mandela being declared one of the most "liked" tweets ever. Among those calling for Trump's ouster was at least one government official. California Congresswoman Jackie Speier cited the 25th Amendment, which was established to enable the removal of anyone who comes to power in the nation's highest office, only to eventually be deemed physically or mentally unfit. "POTUS is showing signs of erratic behavior and mental instability that place the country in grave danger,” Rep. Speier tweeted. "Time to invoke the 25th Amendment."

It would take a 2/3 vote of the Senate to impeach a sitting President. While Presidents Andrew Johnson and Bill Clinton were successfully impeached by Congress both would be acquitted. Richard Nixon often comes to mind when invoking the concept of impeachment, but he actually resigned from office. No President has ever actually been removed by impeachment.
