One of President Donald Trump's most notable campaign promises was to revive the phrase "Merry Christmas."

Others pointed out the strange timing of bringing up Christmas in February.
Not really... it’s February https://t.co/87tUV3NQGD— Liam Stenglein (@Liam Stenglein)1580838704.0
Which is weird, because it’s February. https://t.co/s7BY5GdnUp— Tea Pain (@Tea Pain)1580771733.0
It's February and this the only thing that Eric can think of to brag about. And it's not even true. https://t.co/OOka30cfse— emigre80 (@emigre80)1580783467.0
