In the usually collegial ranks of the Senate appropriations subcommittee, Senator John Kennedy of Louisiana is singing a discordant tune. As one of the influential "cardinals" who oversee the government’s trillion-dollar funding process, his recent actions and statements have raised eyebrows and tempers among his colleagues.

Kennedy, the chair of the subcommittee on energy and water programs, has openly criticized the current state of bipartisan spending talks, likening them to "playacting" and declaring them as "dead as Jimmy Hoffa." His frustrations boiled over this past week when he stalled a package of fiscal 2026 spending bills, demanding a vote against the funding for Congress itself.

His discontent doesn’t stop there. Kennedy is threatening further delays this fall in his own bill, pushing for spending cuts and drawing hard lines that could jeopardize another bill funding the Interior Department. This stance has left his colleagues perplexed and frustrated, including Senator Patty Murray of Washington, the top Appropriations Democrat, who bluntly stated, "He’s breaking it."

Kennedy argues that the political reality in Washington makes any substantial agreement between President Donald Trump and congressional Democrats unlikely, foreseeing a future reliant on short-term spending patches known as continuing resolutions.

Known for his sharp wit and down-home aphorisms, Kennedy's recent approach has marked a departure from his typical style. His pragmatic colleagues on the panel, who are accustomed to making compromises, are finding his new stance particularly jarring.

While not alone in causing disruptions — Democratic Senator Chris Van Hollen also posed challenges over specific issues — Kennedy’s broad critique of the appropriations process itself is unique and unsettling for many, including Senate Majority Leader John Thune, who expressed his surprise at Kennedy’s comments.

Kennedy recently managed to negotiate with Senate leadership for a separate vote on the funding for Congress, allowing him to express his disapproval without opposing broader spending packages focused on Veterans Affairs and Agriculture. However, his broader criticisms and calls for spending cuts continue to alienate his colleagues.

Senator Lisa Murkowski of Alaska reflected on the change, noting that traditionally, members of the Appropriations Committee worked together closely, regardless of party lines. "We don't have that right now, which is unfortunate," she said.

Even as Kennedy faces opposition from within his party, he remains steadfast, involved in discussions with White House budget director Russ Vought about possible spending clawbacks, a move that Democrats warn could implode the appropriations process.

As tensions mount, the standoff continues, with Kennedy at its center, challenging the norms of Senate negotiations and testing the patience and unity of his colleagues. With his insistence on further cuts and his critiques of the bipartisan process, the senator is reshaping his role from a cooperative policy maker to a defiant challenger of the status quo. The outcome of this discord remains to be seen as the Senate struggles to find a path forward in its budgetary responsibilities.
