Senate Minority Leader Mitch McConnell is facing renewed criticism from Republican senators over his leadership following a recent dispute over a bipartisan border security bill.
The bill, which was previously endorsed by McConnell, was strongly opposed by many Republican senators, who believed that it did not sufficiently reduce levels of illegal migration to the United States, with particular opposition over a provision to permit up to 5,000 persons to be processed per day before emergency measures could be enacted.
Though McConnell later voted against proceeding to consider the bill on Wednesday, his detractors in the Senate Republican conference have begun calling for his replacement, while other senators have declined to say whether they support him.
