US President Donald Trump has tweeted a photo of the line to get in to his Pennsylvania rally, taken by CNN journalist Jim Acosta.
The President did not credit Mr Acosta, a journalist he has clashed with on numerous occasion.

Before the rally in Erie, Pennsylvania, Mr Acosta tweeted a photo of the line to get in to the venue.
Shortly after, Mr Trump tweeted out an identical photo of the line to get into the venue.
Though the photo had been cropped, it was clearly identical to Mr Acosta's, and CNN's chief White House correspondent did not miss the opportunity to call the President out.
Mr Trump has not responded to Mr Acosta's tweet.
