Joe Biden’s great-great-grandfather was pardoned by Abraham Lincoln

Moses Robinette was convicted in a civil war-era brawl - but Biden's predecessor gave him a reprieve

Joe Biden's great-great-grandfather was charged with attempted murder after a civil war-era brawl - but pardoned of any wrongdoing by Abraham Lincoln, a newspaper said on Monday, reviving on the US holiday of Presidents' Day the often contentious issue of presidential powers to grant pardons.

Citing documents from the US national archives, the historian David J Gerleman wrote in the Washington Post that Biden's paternal forebear Moses J Robinette was pardoned by Lincoln after Robinette got into a fight with a fellow Union army civilian employee, John J Alexander, in Virginia. Robinette drew a knife and sliced Alexander.
