Don Lemon has slammed Donald Trump for his light work schedule, questioning what the president was doing behind closed doors in the White House.

With Wednesday the fifth day in a row without a public appearance by Trump, the CNN host suggested that, although there’s “no official way for anyone to know how this president spends his days,” one could look to his Twitter.

“We know this president tweets from early morning until late night,” Lemon said. “But I want you to remember, remember during the 2016 campaign, then-candidate Trump said he was going to work really, really hard.”
