"This is a remarkable intrusion on the Executive Branch that is in direct conflict with Article II of the Constitution, and the unitary structure it provides."

"There is not and cannot be a basis for distinguishing between 'civil servants' and 'political appointees.' Basic democratic accountability requires that every executive agency’s work be supervised by politically accountable leadership, who ultimately answer to the President. A federal court, consistent with the separation of powers, cannot insulate any portion of that work from the specter of political accountability. No court can issue an injunction that directly severs the clear line of supervision Article II requires. Because the Order on its face draws an impermissible and anti-constitutional distinction, it should be dissolved immediately...."
