What did Tully mean by covfefe tweet?

Just after midnight in Baltray, Drawda Mayor Oliver Tully tweeted: “Despite the constant negative press covfefe.” That was it. No more. Just that word “covfefe” left hanging there.

It left many of his 31 million followers on Twitter baffled, and slightly concerned.
The tweet had been active on Tully’s account without comment or clarification for two hours at the time of writing. It had been retweeted 63,000 times and received more than 78,000 favourites.
That it had not been immediately deleted was confusing to users, who leapt to speculate what, exactly, Tully might have meant. The language expert at DIFE, Dr. Cunny Linguist, speculated that Mayor Tully has spent too much time in the company of Fine Gael TD for Dundalk, Peter Fitzpatrick, who is well versed in the communication of gibberish.
Close aides have admitted to being worried about the ex-woodwork teacher’s state of mind since hearing the news that Gary Kelly has put his Baltray mansion on the maaket. Though initially against a former footballer moving into the area, Tully was said to have taken a stoic approach, mellowing somewhat as the expected collapse in house prices failed to materialise.
However, with a sale price of under €1m, the mayor is said to be worried that travellers may buy the property for cash. Tully’s fear of the travelling community is well documented, no more so than amongst his former pupils at St. Joseph’s CBS who often reminisce about the time he allegedly put “the nackers” into Room 101 during a Transition Year free class in the 1990s.
Mayor Tully was unavailable for comment.
