Former Attorney General Eric Holder said Thursday that the next Democratic president should considering packing the Supreme Court by adding additional seats.

Holder made the comment during a discussion at Yale Law National Security Group, a spokesperson for Holder confirmed to The Hill.

"In response to a question, Attorney General Holder said that given the unfairness, unprecedented obstruction, and disregard of historical precedent by [Senate Majority Leader] Mitch McConnell and Senate Republicans, when Democrats retake the majority they should consider expanding the Supreme Court to restore adherence to previously accepted norms for judicial nominations," said Patrick Rodenbush, spokesperson for the National Democratic Redistricting Committee, which Holder heads.

Holder, who served under former President Obama, had been considering a 2020 presidential run, but this week officially announced he would not.

Calls for Democrats to pack courts have risen in response to perceived injustices in how Republicans have handled recent Supreme Court nominees.

In 2016, Senate Republicans declined to consider Obama's court pick, Judge Merrick Garland.

Since President Trump's election, two conservative Supreme Court justices, Neil Gorsuch and Brett Kavanaugh, have been confirmed with less than 60 votes in the Senate.

So far, Democratic front-runners have not endorsed the idea of packing courts.

South Bend, Ind., Mayor Pete Buttigieg (D) has said the idea should be given more consideration, though he has not officially backed it.

"I have not reached a considered position on the question of court-packing," he said at a February event in Philadelphia.

"Although I don't think we should be laughing at it. Because in some ways it's no more a shattering of norms than what's already been done to get the judiciary to where it is today."

Buttigieg has taken aggressive stances on Democratic reform, saying in January that the Electoral College should be abolished because it "has made our society less and less democratic."
