The mysterious recurring bruise on the back of Donald Trump’s right hand reappeared on Tuesday, prompting a fresh wave of concern over the president’s health. Trump, 79, was spotted with a healthy dose of flesh-colored concealer on his hand as he was photographed boarding Marine One at the White House on his way to Pittsburgh. Trump was speaking to reporters about Russian President Vladimir Putin when a cameraman spotted his hand and zoomed in for a closer look. White House Press Secretary Karoline Leavitt told the Daily Beast that the bruise is due to the president’s serial handshaking.
