On Tuesday, the Office of the White House Counsel delivered an eight-page letter to Democratic House Speaker Nancy Pelosi (D-CA) rejecting the very legitimacy of the impeachment inquiry threatening this presidency.

The letter was notable not for the conclusion it reached—few suspected that the administration was going to cooperate with House Democrats—but for the broadsides and rhetorical flourishes it featured. That’s because this letter wasn’t fully written by lawyers.

It was crafted, in large part, by President Donald Trump himself.

According to two people familiar with the process, White House Counsel Pat Cipollone had multiple meetings with President Trump in the days leading up to the issuance of the letter. During those meetings with Cipollone, the president would get especially animated when names such as Rep. Adam Schiff (D-CA), chair of the House Intelligence Committee leading the probe into the whistleblower complaint, came up. The sources said that Trump enthusiastically suggested adding various jabs at Democratic lawmakers and would request that their “unfair” treatment of him be incorporated into the letter.
