evidence: Photos shared on Facebook purport to show President Joe Biden with a bruise on his forehead while meeting with the North Atlantic Treaty Organization (NATO) in Poland. [...] The post features three photos of Biden with a mark on his forehead while at the meeting. "Anyone notice President Biden showed up in Poland at the NATO meeting with a new bruise on his forehead? Jill must have delivered the mail or he fell again," the Facebook post purports. [...] There are no credible news reports suggesting the mark on Biden’s head was a bruise. Likewise, the purported claim neither appears on the White House’s website nor its verified social media accounts.
