How Charmin!

President Trump was photographed climbing the stairs to Air Force One as he left Minneapolis on Thursday with what appeared to be a piece of toilet paper stuck to his shoe.

It was unclear if the white paper was, in fact, TP or perhaps a napkin or some other sticky scrap — but he predictably became the butt of jokes on social media.

“I honestly cannot believe it’s taken this long for Trump to board Air Force One with a full strand of toilet paper trailing from his shoe,” @briantylercohen tweeted.

Scott Dworkin, co-founder of The Democratic Coalition, also took a swipe at the commander-in-chief and added a call to reject his nominee to the Supreme Court, Brett Kavanaugh.

“.@realDonaldTrump-Take the toilet paper off your shoe. #VoteNo,” Dworkin tweeted.

In his crack, @JClaudeDeering said: “Does that toilet paper have some Trump stuck on it?”

The offending piece of paper became dislodged right before Trump entered the aircraft and was left atop the stairs.
