Just after midnight on May 31, President Donald Trump posted one of his most controversial tweets ever.
It wasn't controversial because of politics, but rather because of a single word, reports The New York Times.
At 12:06 a.m., Trump tweeted, "Despite the constant negative press covfefe," but that's all the tweet said. By 1 a.m., the mysterious post had consumed Twitter, mostly with humorous speculation on the meaning of "covfefe," which is generally assumed to be a typo of the intended word, "coverage."
At least one person compared it to the classic movie "Citizen Kane," in which a reporter searches for the meaning of "rosebud," which was the dying word of a newspaper magnate.
In another movie reference, it was joked that "covfefe" is what actor Bill Murray silently whispered to Scarlett Johansson at the end of the movie “Lost in Translation.”
The London Independent wondered if Trump's keyboard might have been randomly struck, noting that the iPhone -- the brand used by the president -- doesn't auto-correct the word "covfefe" because it's not similar enough to any other real word. There's even a conspiracy theory circulating which claims that Google translates "covfefe" as "Soviet."
By 3 a.m., in typical American tradition, “covfefe” T-shirts were being sold online.
After about six hours of going viral, the president’s mysterious tweet was finally deleted, either by himself or a staff member. At 5:09 a.m., Trump himself got in on the fun: “Who can figure out the true meaning of ‘covfefe’ ???” he tweeted. “Enjoy!”
On a more serious note, the fact that the tweet was deleted might be against the law, notes The Independent. By law, the president's communications are required to be preserved, and the White House has been instructed by the National Archives that it must "capture and preserve all tweets that the President posts… including those that are subsequently deleted."
But the president is not required to prove that he's done so, and although the White House has claimed that Trump's deleted tweets are being recorded, it hasn't offered any proof yet.
Trump's posts that include typos or other mistakes are regularly removed and re-posted after they have been corrected. So far, the "covfefe" tweet has not been re-posted on his Twitter account, though copies of it have been re-posted thousands of times on the internet.
As for the "covfefe," whether or not it makes it into the dictionary remains to be seen.
