I think he's saying that many people on a bi-partisan basis has been pushing for this for a long time, which would make the timing less suspicious as it has been picking up steam for a long time.
Ie lots of people pushing a change, not pushing a theory.
If there was no conflicting evidence, then maybe. But if you read the newspaper, you know this has been in the works for a very long time, and again from both Republicans and Democrats.
AG Barr has been pushing to get this out before the election, over objections of his own attorneys:
"He [Barr] pushed career Justice Department attorneys to bring the case by the end of September, prompting pushback from lawyers who wanted more time and complained of political influence."[1]
You are correct. But that doesn't mean all of the Democrats and other Republicans who have been pushing for this for years have suddenly vaporized from history.
