Although the word covfefe was considered most likely a misspelling of the word “coverage,” Spicer, Trump’s top interpreter as White House press secretary, didn’t offer that explanation. Instead, speaking for a boss who does not admit to mistakes, he insisted — against all appearances — that this was no mistake.

Spicer told reporters that the public should not be concerned that the president sent what the questioner called “somewhat of an incoherent tweet.”

“The president and a small group of people know exactly what he meant,” Spicer said.

Whatever it was, Trump’s tweet did raise concerns about the health of a president who is 70 years old, overweight and just returned from a jam-packed eight-day trip across the Middle East and Europe. Conservative writer David Frum, a former aide to President George W. Bush, tweeted his speculation that Trump may have experienced a spasm while his Twitter feed was live, and lost consciousness.
