Mitch McConnell, the Minority Leader of the Senate (R-KY), made the shocking recommendation that Republicans stop the Senate’s pro-migration border legislation.

The first procedural voting was scheduled for Wednesday. Although it is probable, it is not known if Majority leader Chuck Schumer will push ahead.

McConnell said that the majority of Senate Republicans planned to vote against the bill either because it was unconstitutional or they wanted more time. This is according to Punchbowl News.

The long-time Republican leader spoke in favor of this deal, and didn’t express any personal reservations about the legislation.

McConnell told Punchbowl that the mood of the country had changed since the negotiations began. McConnell, who is McConnell’s biggest supporter in the Senate, and Democrat leaders had agreed at that time to pair foreign aid for Ukraine with a border compromise.

Democrats, who are also in general in favor of helping Ukraine in its stalemated conflict against Russia, have used McConnell’s enthusiasm for Ukraine assistance against Republicans by dangling an exchange proposal for a border compromise as a way to help the European nation.

The deal was praised by the majority leader, Chuck Schumer. Schumer said to reporters that he had never worked with McConnell as closely on any piece legislation before.

The bill’s publication confirmed that details of the secretive agreement, which McConnell and his Republican lead negotiator, Sen. James Lankford, R-OK, denied, had been leaked. McConnell changed his plan on Monday night due to the overwhelming opposition.

According to the Huffington Post, even Lankford who continued to champion the deal up until Monday’s Senate Republican Conference Meeting, did not indicate after the meeting whether he would vote Wednesday to approve the deal that he negotiated.

The plan would put into law many open border policies that Biden has implemented that have led to an influx of migrants that has overwhelmed the law enforcement along the southern border.
