Everything is subject to “executive privilege.” Everything. Nobody can give anything to any Congressional hearing ever because “executive privilege.” It’s an eternal law and it covers everything in this universe and all others.

The White House on Tuesday invoked executive privilege to bar former White House counsel Donald McGahn from complying with a congressional subpoena to provide documents to Congress related to special counsel Robert S. Mueller III’s investigation.

In a letter to the House Judiciary Committee, White House counsel Pat A. Cipollone said McGahn does not have the legal right to comply with its subpoena for 36 types of documents — most relating to Mueller’s nearly two-year probe of Russian interference in the 2016 election. Rather, Cipollone argued the committee needed to send the request to the White House — and even hinted that they would assert privilege to block the information.

Because executive privilege is an absolute, and not subject to the whims of such a trivial body as the legislative branch.

McGahn emerged as a central player in Mueller’s findings, a senior confidante who documented in real-time Trump’s rage against the Russia investigation and efforts to shut it down. Democrats were hoping to have him testify for a national television audience.

The special counsel has identified two episodes in which McGahn was a critical witness and in which investigators say they have substantial evidence Trump was engaged in obstruction of justice that would normally warrant criminal charges.

In mid-June of 2017, Trump tried to pressure McGahn to intervene with the Justice Department to try to push for Mueller’s removal from office based on alleged conflicts of interest, the report said; in February 2018, Trump summoned McGahn to the Oval Office and urged him to deny a news account that suggested the president asked for his help in ousting Mueller.

But Trump is His Majesty King Executive, so none of that matters. God save the King Executive.
