Republican senators declare bipartisan project to impose stricter border security laws dead. After a meeting of members of that party in the Senate, McConnell told the press that it is clear that "we have no real chance of passing the bipartisan law" on border security, which they negotiated with the Democrats.
Within minutes of the bill's release on Sunday, Republican senators began speaking out against it. On Tuesday, opposition reached a fever pitch, even within McConnell's team. At that point, it became clear that they would not reach the 60 votes needed to prevent a delaying maneuver when the bill went to the full Senate on Wednesday.
