House republicans aren't debating the provisions of the bill. They are saying that new legislation isn't necessary and that they won't even attempt to negotiate. This is a new position and coincides with Trump's public stance against any new legislation. He's very open about it and Johnson has said that he has been in contact with Trump on the issue.
This is all public record.
Republicans thought they could win political points by tying the border to Ukraine and Israel funding, but Dems surprised them by supporting "the most conservative border bill in a generation", according to multiple conservative Senators, media pundits, the Border Patrol Union and others. So now republicans, who claimed they wanted new legislation, won't even debate what at a minimum should be a great starting point for a final bill that addresses many of their concerns.
Everyone knows who is pulling the strings with Johnson and House republicans. This is 100% because of Trump.
I said when the GOP won such narrow control of the House that they would have been better off being in the minority because now the MAGA loons would be running the show and that's exactly what we are seeing. Just in the last twenty-four hours, we have seen the first failed impeachment vote since Andrew Johnson, Comer's committee has gone silent after getting called out for mischaracterizing private testimony and failing to find the goods on Biden, Gaetz, MTG and crew didn't care for the entirely logical and predictable loss for Trump on the presidential immunity issue, so they are going to pass a meaningless resolution that Trump didn't lead an insurrection (watch as their concern about insurrection charges gets very personal in the future) and of course the total failure on the border/Ukraine/Israel deal.
It's easy for Dems to look unified in the face of such rank incompetence.
EDIT: Very interesting comments from Lankford.
