White House Press Secretary Karoline Leavitt offered an explanation after President Donald Trump was pictured in Switzerland with new bruising on his left hand.
“At the Board of Peace event today in Davos, President Trump hit his hand on the corner of the signing table, causing it to bruise," Leavitt told CNN.
The White House has previously blamed Trump's bruising on aspirin and shaking hands.
It was not clear if there was any video proof of the president hitting his hand on a table.
A bump generally takes a few hours to days to show up as a blue or purple bruise, according to medical experts.
