When US president Donald Trump was heckled by a union worker in Michigan on Tuesday, the Republican appeared to respond by saying “f*** you” and giving the employee in question the middle finger – and the White House has said such a response was “appropriate and unambiguous”.

President Donald Trump made an obscene gesture with his middle finger and mouthed an expletive to a factory employee who shouted at him during a tour of a Ford plant in Michigan on Tuesday.

TMZ has obtained video of Trump giving the middle finger to a heckler at a Ford plant in Detroit who shouted what appeared to be the phrase "pedophile protector" at him.
