Supreme Court Justice Clarence Thomas issued a dire warning about governance in Washington during a speech at the Heritage Foundation on Wednesday night.

Thomas’ speech comes three days after the occasion of his 25th anniversary on the court, and he used the opportunity to sound the alarm about destructive politics in D.C. Thomas said he was hopeful the confirmation process to fill the void created by Justice Antonin Scalia’s death could be improved, but that the political environment is toxic.
