A thin piece of paper that resembled toilet tissue or a napkin was stuck to President Donald Trump's shoe as he boarded Air Force One on Thursday.

When Trump reached the top of the stairs, he turned back and waved to the crowd. The paper got dislodged as he entered the cabin.

Four other people walked up the steps after Trump. The last person spotted the cloth and picked it up with his hands.
