In a surprising turn of events, Senator Josh Hawley (R-Mo.) has thrown a wrench into Senate Republican Leader Mitch McConnell's (Ky.) plan to confirm two former aides to important federal agencies. This move has further escalated the ongoing feud between the first-term conservative senator and the veteran party leader.

On Wednesday, Hawley sent a letter to McConnell, expressing his desire for more time to thoroughly vet the nominees supported by McConnell. The nominees, Andrew Ferguson and Todd Inman, were scheduled to be approved by unanimous consent alongside a list of Biden's nominees. However, Hawley believes that accepting this package deal without careful examination could have significant consequences.

Hawley stated in his letter, "By agreeing to such a negotiated package in exchange for just a few Republican appointees you have personally deemed a priority, I believe we risk giving away too much." He specifically pointed to Ferguson's nomination for the Federal Trade Commission and Inman's nomination for the National Transportation Safety Board, emphasizing the need for a detailed understanding of their views on important issues such as tech regulation and rail safety.

At present, three Democratic appointees occupy the five-member Federal Trade Commission, leaving the two Republican spots vacant. As for the National Transportation Safety Board, one seat remains unfilled, while the chairwoman was appointed by President Biden and the other members were appointed by former President Trump.

Hawley's intention is clear: he will block the nominees from advancing on the Senate floor until his concerns are addressed. He wrote in his letter, "I am currently withholding my consent for these nominees to be confirmed without a floor vote...until I and others can evaluate satisfactory responses to these important policy questions."

When asked about Hawley's holds, McConnell declined to comment, choosing to remain tight-lipped as he headed back to his office from the Senate floor.

Andrew Ferguson, Biden's nominee for the Federal Trade Commission, currently serves as the solicitor general of Virginia and previously worked as McConnell's chief counsel. Todd Inman, nominated by Biden for the National Transportation Safety Board, formerly served as the chief of staff to former Transportation Secretary Elaine Chao, who is married to McConnell. Inman also has a history of working as a campaign aide to McConnell.

This latest dispute between the two Republican senators is just another chapter in a longstanding feud that began in November of last year, when Hawley called for a change in leadership and openly supported Senator Rick Scott's (R-Fla.) challenge against McConnell.

It's worth noting that the tension between the two stems from Hawley's amendment in the final negotiations over the defense bill, which McConnell opposed and successfully stripped despite receiving approval with 61 votes on the Senate floor. The GOP leader cited concerns about budget implications and an unfunded mandate, while Hawley argued that he had proposed ways to cover the added costs and that inclusion of individuals from the St. Louis area would have minimal impact on the program's expenses.

As the battle between Hawley and McConnell rages on, the fate of the nominees hangs in the balance. The upcoming weeks will reveal whether a resolution can be reached or if this feud will continue to undermine party unity.
