Um.... yeah. We knew that already.
The point obviously never was eliminating supposed waste.
It was, blatantly, a purge, meant solely to get rid of anyone who wasn't a Trump sycophant, anyone who was currently or ever had been involved in investigating the myriad lies, scams and crimes of Trump and his cronies and/or anyone who might stand in the way of their future lies, scams and crimes.
Did you really not know that? Where have you been the last few months?
It's things like this that make me suspect that the Republicans are actively trying to destroy the US.
If the goal is to benefit the US broadly, and into the future, there's no possible way that discouraging alternatve energy (or EVs) is a sound strategy. It's basically just handing China hegemony in the coming world order.
So it's pretty much either the case that Republican politicians are impossibly stupid, or that their actual goal is to guarantee Chinese hegemony and reduce the US to a bankrupt has-been.
