A Harvard Law School lecturer is demanding that Democrats pack the Supreme Court with liberals as soon as they regain power in Congress.

Shortly after Associate Justice Anthony Kennedy announced his retirement, Ian Samuel tweeted that Democrats should "pack the courts."

Samuel said the phrase should be on par with "abolish ICE," a recent sentiment argued by the left in protest of President Trump’s “zero tolerance” policy at the border.

Appearing on "Tucker Carlson Tonight" Tuesday, Samuel said that the Supreme Court shouldn't be partisan and subject to "ideological swings."

He said, though, that his issue with the Supreme Court is that 14 of the last 18 justices have been appointed by Republican presidents.

"The balance on the Supreme Court is way out-of-whack with what people have voted for," Samuel said, adding that in order to restore the court's balance, it should be expanded in order to add more liberals.

The centrist Kennedy's retirement will give Trump the opportunity to move the court solidly to the right, and a vacancy on the court could become a key issue in the midterm elections.

Carlson responded to Samuel by saying that polling data has shown that recent decisions by the Supreme Court have fallen within the center line of public opinion.

"Actually, there isn't a problem other than [that] Democrats don't get to do their will with the courts to the extent you wish they could," he said.

He added that Samuel's suggestion of court-packing would delegitimize the court in the eyes of the public.
