Rep. Alexandria Ocasio-Cortez, D-N.Y., on Wednesday introduced articles of impeachment against Supreme Court Justices Clarence Thomas and Samuel Alito, saying that their refusal to recuse from certain prominent cases “constitutes a grave threat to American rule of law.”

In a statement, the New York congresswoman said that justices’ refusal to step aside from cases “in which they hold widely documented financial and personal entanglements” has created an “unchecked corruption crisis on the Supreme Court.”

This, she said, “constitutes a grave threat to American rule of law, the integrity of our democracy, and one of the clearest cases for which the tool of impeachment was designed.”

The high court did not immediately return a request for comment.
