Sarah Huckabee Sanders' 3-year-old just tweeted a bunch of covfefe

White House principal deputy press secretary Sarah Huckabee Sanders' Twitter account posted a rambling series of emojis, letters and numbers on Saturday morning.

Sanders, who regularly stands in for White House press secretary Sean Spicer, didn't immediately delete the tweet, which features traffic lights, world maps, castles, airplanes, trains and ships.

It turns out the tweet, with its various forms of cartoon transportation, wasn't a nod to President Trump's "Infrastructure Week." Rather, it was the work a 3-year-old.

"This is what happens when your 3 year old steals your phone," she later tweeted. "Thanks Huck! #neverleaveyourphoneunlocked."

For a moment, the unexplained tweet seemed reminiscent of another bizarre White House post: Trump's now infamous "covfefe" tweet.

The White House never explained what Trump meant when he said, "Despite the negative press covfefe." However, Spicer said the midnight tweet — which was later deleted —wasn't a typo. "The president and a small group of people know exactly what he meant," he added.
