No law was broken in Paul's question. He was discussing two key individuals... How should he know who the whistleblower is if even Schiff doesn't. Nope... Paul was perfectly right to ask the question and Roberts wrong in blocking it. There is no law preventing media and Congress from revealing the whistleblower (who should NOT be hidden anyway, just protected from recrimination of course)... just the DOJ alone is prevented.
Senate should not be calling witnesses except ones that were already called in the House and prevented from cross-examining there. But their testimony was not needed as the evidence exonerates Trump completely... The Senate GOP took a mighty step away from the swampiness with their bold action and standing up to the bullying Democrats and house managers who failed in THEIR SOLE DUTY to bring forth a case -- but since there was no crime at all and no abuse of power, there was no case to bring.
You need to start looking at facts and not what MSNBC tells you.
