Chief Justice John Roberts has transferred judicial misconduct complaints filed against Justice Brett Kavanaugh during his confirmation process to a Colorado-based federal appeals court, according to a new letter Wednesday.

The more than a dozen complaints pertain to statements Kavanaugh made over the course of his confirmation hearings in the Senate and were filed with the U.S. Court of Appeals for the District of Columbia Circuit, on which Kavanaugh served for 12 years before he was confirmed to the Supreme Court.
