Chief Justice John Roberts blocked Republican Kentucky Sen. Rand Paul’s question because it named the alleged whistleblower at the center of President Donald Trump’s impeachment trial.

It was the second straight day that the chief justice shot down a question from Paul, which included the name of the alleged whistleblower, who filed a complaint about Trump’s July 25th phone call with Ukraine President Volodymyr Zelensky.

“The presiding officer declines to read the question as submitted,” Roberts said after Paul submitted his question.
