The legality is settled. Democrats have carte blanche and Republicans are persona non grata. It's the law.

TRUMP KNEW THE LAW AND THE LAW CLEARLY STATES THAT A REPUBLICAN ASKING AN UNETHICAL QUESTION IS GUILTY OF RACKETEERING. A DEMOCRAT ASKING AN UNETHICAL QUESTION AND THEN PERFORMING AN ILLEGAL ACT IS LEGAL. AS LONG AS IT PUTS A DEMOCRAT IN ANY PUBLIC OFFICE. THE ENDS JUSTIFY THE MEANS. IT'S THE LAW.
