Donald Trump campaign tweets controversial photo

WASHINGTON, July 15 (UPI) -- Donald Trump's campaign tweeted an image that appeared to contain a photo of Nazi soldiers.

The image, tweeted Tuesday and later deleted, featured Trump, the American flag and the White House. At the bottom, superimposed onto the American flag, was a photo that appeared to show Nazi German soldiers.

A statement from the Trump campaign said the image was created by an intern who used a stock image of the flag and did not notice the soldiers.

Meanwhile, Trump has increased security after threats were sent to him via Twitter from someone claiming to be escaped drug boss Joaquin "El Chapo" Guzman.
