A fake presidential seal appeared behind President Trump Donald John TrumpSteele Dossier sub-source was subject of FBI counterintelligence probe Pelosi slams Trump executive order on pre-existing conditions: It 'isn't worth the paper it's signed on' Trump 'no longer angry' at Romney because of Supreme Court stance MORE onstage at an event for conservative student group Turning Point USA this week.

The fake seal was only briefly visible as Trump walked onstage, replaced by the authentic one for the remainder of the speech, but an aide to Turning Point has reportedly been fired over what was either a startling error or a deliberate prank.

Here are four differences between the genuine seal and the one that appeared behind the president on Tuesday.

The eagle

While the presidential seal features a standard eagle, the one behind Trump this week featured a double-headed eagle. Double-headed eagles are typically associated with empires and have appeared in other countries’ iconography as well, including the coats of arms of the Austrian Empire and Serbia.

Resemblance to the Russian Federation coat of arms

In addition, the eagle makes the false seal bear a resemblance to the coat of arms of the Russian Federation, which is itself based on the coat of arms used in czarist Russia. The original double-headed eagle coat of arms was discontinued after the Russian Revolution in 1917 in favor of the recognizable Soviet hammer and sickle imagery but the eagle was restored in 1992 after the dissolution of the USSR.

The motto

The standard presidential seal bears the national motto “E pluribus unum,” Latin for “out of many, one.” The fake seal behind Trump at the Turning Point event instead featured the phrase “45 es un títere,” Spanish for “45 is a puppet.” Trump famously pushed back against his then-opponent Hillary Clinton Hillary Diane Rodham ClintonFox News poll: Biden ahead of Trump in Nevada, Pennsylvania and Ohio Trump, Biden court Black business owners in final election sprint The power of incumbency: How Trump is using the Oval Office to win reelection MORE’s characterization of him as a “puppet” of Russian President Vladimir Putin Vladimir Vladimirovich PutinPutin nominated for Nobel Peace Prize Navalny released from hospital after suspected poisoning Ex-Trump national security adviser says US leaders 'making it easy for Putin' to meddle MORE at the 2016 presidential debates.

The eagle’s claws

While the eagle on the real seal bears several arrows in its right talon, the one on the doctored seal is bearing golf clubs, an apparent reference to Trump’s frequent visits to the several golf clubs he owns. Trump has spent 210 days at his golf properties while in office, according to NBC's tracker.
