At a press conference today, Donald Trump lamented the fact that the letter accusing his SCOTUS nominee, Brett Kavanaugh, of sexual assault was only made public a few days ago. Trump says the Democrats should have released the letter three months ago, and insisted it was not released three months ago as part of a political maneuver to cause trouble at the last minute by obstructing his desired deadline of having Kavanaugh confirmed before the congressional midterm elections in November. Trump claims Democrats failed to release the letter three months ago as part of a plan to "resist" and "obstruct" his preferred timeline.
Trump seems unaware that Senator Diane Feinstein (D-CA) only received the letter on July 30, only one and one-half months ago. She was asked by it's author to keep it confidential. She referred the letter to the FBI. It was only released after it leaked and became a subject of press reports.
Contrary to Trump's claim, and despite his confusion and befuddlement, Democrats did not hold the letter, hide it, or wait to spring it on the public late in the process (a timetable set by Trump, not the Constitution.)
