Donald Trump has been photographed colouring in an American flag wrong.

The US President was visiting children at a hospital in Ohio with his wife Melania when he sat down to colour in some pictures with children.

A photo tweeted out by secretary of the US Department of Health and Human Services Alex Azar showed Mr Trump sitting with partially coloured-in flag. Twitter users were quick to notice while the top stripe was correctly drawn in red, Mr Trump left the next two white and the coloured the fourth one blue.
