A Republican political action committee has mocked Donald Trump over cheating claims by posting a clip of Biff Tannen from the Back to the Future films.

The Lincoln Project, known for its frequent scathing attacks and political adverts against the president, posted the clip on Twitter of Biff, played by Thomas F Wilson, tormenting George McFly to make sure he completes homework on his behalf.

“Think McFly, think. I’ve got to have time to re-copy it. Do you realise what would happen if I handed my homework in your handwriting? I’d get kicked out of school. You wouldn’t want that to happen would you?” the renowned bully says in the clip from the hit 1985 movie.

The jibe comes in light of allegations in Mr Trump's niece's book, scheduled to be published next week, that the president had paid someone to take the SATs on his behalf.

Mary Trump alleged that the high score her uncle earned dishonestly helped him later gain admittance as an undergraduate to the University of Pennsylvania’s prestigious Wharton business school.

She also says that her uncle sees “cheating as a way of life”.

Biff the bully is famously recognised as having been based on Mr Trump, with creator Bob Gale having announced in 2015 that MrTrump had acted as inspiration for the character.

The Lincoln Project posted the clip from the film in response to an earlier tweet that read: “Look, if you were @realDonaldTrump, you’d have paid someone to take the SATs for you too.”
