It's an especially concerning day to be living in Donald Trump's America.

Shortly after House Speaker Nancy Pelosi stood outside the White House this afternoon and literally said that Trump "had a meltdown" and canceled an "all-Member classified briefing" on the dangerous situation he's caused in Syria, Fox Business anchor Trish Regan tweeted a copy of what she said was a letter from Trump to Turkish President Recep Tayyip Erdogan.

In the letter, dated Oct. 9, Trump asks Erdogan to "work out a good deal," warns him not to "be a tough guy," and says that history will forever look upon him as "the devil" if he is "responsible for slaughtering thousands. Trump ends the letter by saying, "I will call you later."

The language in the letter was so bizarre, informal, and unhinged that upon seeing it on social media, many questioned whether it was actually real.

Though there's a great deal of doubt online,New York TimesWhite House Correspondent Katie Rogers and others have confirmed the letter's authenticity.

While members of Congress and Pelosi publicly and repeatedly voiced concern over the president's erratic behavior, much of Twitter was stunned by the unusual letter's existence.

It's one thing to read yet another of the president's middle of the night tweet-rants, but seeing the exclamation points and non sequiturs laid out on official White House letterhead is quite another.
