It’s pure posing, trying to pin the blame on Democrats for not accomplishing the impossible. The article lays out how they’re not even trying to pretend they’re negotiating in good faith. FTA:

In another absurdity, Republicans have said publicly that Democrats must agree to reduce illegal border crossings by more than 50 percent. But that’s a fuzzy demand: It’s unclear how policy changes could dramatically slash the number who attempt to enter and simply get intercepted by law enforcement. When Democratic staffers sought clarification on this point, the sources say, they got nothing back.

What’s really bizarre about the impasse is that Republicans should support much of what’s in Biden’s initial request for border security funding. After all, it would also fund expedited asylum processing, which could reduce the window for migrants to exploit the system and prompt faster removals for those who don’t qualify. Aren’t those things Republicans want?
