U.S. Supreme Court nominee Neil Gorsuch may have helped cement his chances for confirmation Wednesday night by telling senators that President Donald Trump’s critical tweets of federal judges were “disheartening” and “demoralizing.”

Gorsuch’s comments could have the effect of telegraphing to the legal establishment and to the Supreme Court itself that he embraces the importance of judicial independence. An unwritten rule in Washington discourages personal attacks on federal judges by presidents as a threat to the judiciary’s role in checking executive branch overreach.
