President Donald Trump on Tuesday made a show of flicking dandruff from the suit collar of visiting French President Emmanuel Macron, saying it was a sign of the two leaders' "very special relationship."

Trump made the surprise gesture as Macron, the first foreign leader to be honored with a state visit in Washington since Trump took office 15 months ago, stood at his side for a photo opportunity in the White House's Oval Office.

"We have a very special relationship; in fact I'll get that little piece of dandruff off... We have to make him perfect, he is perfect," Trump said to a laughing Macron. (Daily Mail)
