In a pivotal 2011 Second Amendment case, Kavanaugh wrote a dissenting opinion when the D.C. Circuit Court upheld a District of Columbia ordinance banning most semi-automatic rifles.
Kavanaugh argued that the Second Amendment included the right to own semi-automatic rifles.
Kavanaugh wrote that the Supreme Court has found that handguns — "the vast majority of which today are semi-automatic" — are constitutionally protected.
"Semi-automatic rifles, like semi-automatic handguns, have not traditionally been banned and are in common use by law-abiding citizens for self-defense in the home, hunting, and other lawful uses," he wrote.
Citing his upbringing and working life in the area, Kavanaugh said he was "acutely aware" of the area's gun, drug and gang violence.
"But our task is to apply the Constitution and the precedents of the Supreme Court, regardless of whether the result is one we agree with as a matter of first principles or policy," he wrote.
