Sadly, no. That response in 2018-2021 would have been urgent, appropriate. By waiting until 2023 when reports were coming out in '21 that the Darian Gap was failing and '22 that it had failed, Biden did in fact drop the ball. The administration chose to try to work with/through Central American governments who, frankly, hadn't dealt with screwworms in over a generation and were poorly equipped or completely clueless. Also, it's worth noting, this facility was relatively inexpensive to operate at less than $20M/year. We had a beautiful system in place but Republican ignorance and Democrat pussyfooting has put us in a terrible position. The sunbelt population boom of the last 50 years was not just about AC.

Biden was inaugurated in '21. Why did it take multiple years for that funding to be budgeted?

I'd assume at least 10x was asked, and it took years for the funding to arrive
