The mysterious bruise was first noticed in February, but the White House chalked it up to Trump's frequent hand-shaking

Concern for the president's health has increased as more images show bruising on his hands and swelling in his legs.

President Donald Trump went concealer-free on Monday, showing a dark bruise on the back of his right hand while signing executive orders in the Oval Office. Sitting at the Resolute Desk, Trump appeared to be covering up the back of his right hand by placing his left hand on top of it while speaking with reporters.
