Trump threatens Supreme Court fight in rage tweet against impeachment: 'No crimes by me at all!'

President Donald Trump threatened to seek relief from the U.S. Supreme Court if he's impeached by Congress -- even though, as he insisted in capital letters, he "did nothing wrong."

Trump again spent the morning tweeting, focusing for a bit on possible military action at the U.S.-Mexico border, before turning his attention to the prospect of impeachment.

"The Mueller Report, despite being written by Angry Democrats and Trump Haters, and with unlimited money behind it ($35,000,000), didn’t lay a glove on me," Trump tweeted. "I DID NOTHING WRONG. If the partisan Dems ever tried to Impeach, I would first head to the U.S. Supreme Court."

Special counsel Robert Mueller's 22-month investigation cost taxpayers more than $25 million, about $10 million less than the figure Trump cited, and it's not clear how Trump is justifying his threat to fight impeachment in the Supreme Court.

Harvard Law professor emeritus Alan Dershowitz, a staunch Trump defender, has argued the Supreme Court could overturn impeachment, although the court has previously ruled that it should not review impeachment.

"Not only are there no 'High Crimes and Misdemeanors,'" Trump tweeted, "there are no Crimes by me at all. All of the Crimes were committed by Crooked Hillary, the Dems, the DNC and Dirty Cops - and we caught them in the act! We waited for Mueller and WON, so now the Dems look to Congress as last hope!"
