(CNN) President Donald Trump pardoned two men on Tuesday who were involved in a dispute with federal authorities over federal land usage that sparked the takeover of a wildlife refuge in Oregon.

Dwight Hammond Jr. and his son Steven Hammond were granted executive grants of clemency by Trump, according to a White House statement. The father-son duo are cattle ranchers and were convicted in 2012 of committing arson on federal lands in Oregon.

"Justice is overdue for Dwight and Steven Hammond, both of whom are entirely deserving of these Grants of Executive Clemency," the statement read.

The Trump White House took aim at the Obama administration as well, adding that it filed an "overzealous appeal" that led to the two men's five-year prison sentence: "This was unjust."

Dwight Hammond has served approximately three years in prison, and his son Steven has served four years, according to the White House.
