Presidential candidate Pete Buttigieg has been accused of plagiarising Barack Obama in several campaign speeches.

In a compilation video featuring side-by-side comparisons of the two men's speeches, Mr Buttigieg is shown using almost the exact same words as Mr Obama on multiple occasions.

The embarrassing video, assembled by Brennan Murphy at video agency The Recount, comes as Mr Buttigieg faces mockery for a tweet in which he seemed to borrow from one of the speeches in question.

Describing how the audience at a campaign event used their phone screens when the room hit by a power cut, Mr Buttigieg tweeted: “If we can light up a high school gym – we can light a neighborhood.

“If we can light up a neighborhood – we can light a city.

“If we can light up a city – we can light up our country

It's absolutely a send up of US gun culture lol.
