Watergate whistleblower and Nixon White House counsel John Dean on Friday predicted Brett Kavanaugh would lead a 5-4 Supreme Court to further enhance presidential power that already is “quickly slipping out of bounds.”

During Senate Judiciary hearings on Kavanaugh’s nomination, Dean warned that, if the judge is confirmed, the Supreme Court “will be the most pro-presidential powers Supreme Court in the modern era.” Evidence that the court is already heading in that direction, he said, is the 5-4 decision in June upholding President Donald Trump’s ban on the entry into the United States of foreign nationals from certain predominantly Muslim countries.
