When asked about the news on Oct. 5 that new border wall construction would indeed commence under his administration, Biden told reporters: “The border wall — the money was appropriated for the border wall. I tried to get to them to reappropriate it, to redirect that money. They didn’t. They wouldn’t. And in the meantime, there’s nothing under the law other than they have to use the money for what it was appropriated. I can’t stop that.”
Trump intended to build the wall with no environmental assessments or permits and congress wrote in a waiver since the border was “an emergency” but Biden chose to rescind the emergency declaration and follow the long-established federal construction process instead of using the waivers which does indeed slow things down.
That’s nothing like what is happening with Musk “deleting” entire departments or unilaterally stopping funding because he doesn’t like the phrasing of the grants.
