According to Donald Trump, Donald Trump is solely responsible for coining the term "fake news," Making America Great Again, and of course, bringing the phrase "Merry Christmas" back into the White House.

On Wednesday, Donny T. delivered a tax reform speech in St. Charles, Missouri, that started and ended with a focus on Christmas. Trump bragged and bragged about how heis the one bringing Christmas back to America, acting as though former presidents straight-up banned the holiday from the calendar or something.

MSNBC decided to investigate his claims, and believe it or not, it turns out Trump's predecessor, Barack Obama, didin fact have those two words in his vocabulary. Can you imagine?

"I was the one who said we're gonna have Christmas again," Trump said opening his speech. "With Trump as your president we are going to be celebrating 'Merry Christmas again."

WRONG.

MSNBC's Chris Hayes trolled Trump by delivering a special Christmas-themed report complete with a super-cut of Barack and Michelle Obama saying "Merry Christmas" over their eight years in the White House.

As Hayes said, "Tis the season for more ridiculous lies about the prior president, Barack Obama."
