Trump tweeted "covfefe" late Tuesday night, seemingly attempting to write the word "coverage" in a tweet critical of the press.
He eventually deleted the tweet and joked about the meaning of the made-up word, telling his followers to "Enjoy!"
But when asked about the implications of the president's late-night tweeting, Spicer refused to admit the word was an innocent human error, instead commenting that "the president and a small group of people know exactly what he meant."
Spicer has been under fire after a string of mishaps in recent weeks. At the daily White House press briefing on Tuesday, he struggled to provide any actual information to reporters who asked about climate change, his team's ties to Russia, health care legislation and more.
