An aide has been fired following an incident this week at an event for conservative non-profit group Turning Point USA, where a doctored presidential seal appeared behind President Trump.

A White House spokesman, Judd Deere, said that officials "never saw the seal" before it was projected on a screen behind Mr Trump as he was introduced at the organisation's teen summit.

According to The Washington Times, the fake seal was visible for around 80 seconds before it was taken down.

On Thursday, Turning Point USA announced that the aide responsible for the blunder had been fired. The seal featured pro-Russian imagery, including a two-headed eagle that nods to the Russia Federation's coat of arms and the words "45 es un titere", Spanish for "45 is a puppet" and referring to the 45th president of the United States.

The 13 arrows in the eagle's left claw on the original seal were replaced with 13 golf clubs, while the eagle's right claw held cash instead of an olive branch.

The doctored seal was designed by a former Republican voter from Virginia, The Washington Post reported. After Mr Trump won the election in 2016, Leazott designed the seal as a "goofy thing for some people I knew," he said. He voted for George W. Bush twice but is not a fan of Donald Trump.
