President Trump may not agree, but on Monday night Federal Judge Ketanji Brown Jackson ordered McGahn to testify before the House of Representatives, stating that ‘Presidents are not kings.’
This is in reference to the White House trying to prevent senior Trump officials from testifying in the Russian investigation. Trump had pushed for blanket immunity.

In the stinging rebuke of Trump, the judge quoted Founding Fathers James Madison and Alexander Hamilton and French diplomat Alexis de Tocqueville, saying:
“Stated simply, the primary takeaway from the past 250 years of recorded American history is that Presidents are not kings,” Jackson wrote.
“It is indisputable that current and former employees of the White House work for the People of the United States, and that they take an oath to protect and defend the Constitution of the United States,” the judge added.
This is a big win for the Democrats and hopefully sets a precedent — meaning that other hold outs such as Mick Mulvaney would be now forced to testify.
