The U.S. Senate adjourned for a weeklong Memorial Day recess on Thursday, delaying a vote on a significant $70 billion immigration bill following substantial Republican opposition to a controversial "anti-weaponization" fund championed by former President Donald Trump.

Republicans had planned to advance the bill, but internal deliberations revealed deep concerns about provisions related to the "anti-weaponization" fund, which is intended to compensate allies who claim to have faced injustices under the current administration. The bill also includes funding for White House security, including a ballroom, which also faced scrutiny.

Acting Attorney General Todd Blanche met with Senate Republicans to address the mounting outrage over the "anti-weaponization" fund, but the session reportedly devolved into shouting. Some senators, including Trump supporters, expressed fears that the fund could jeopardize the Republican Senate majority. Blanche's attempt to placate senators by suggesting they could also apply for funds from the pool seemed to backfire.

The delay means that any potential legislative action to rein in Trump's spending priorities will be postponed until after the recess. Republicans are exploring various avenues to implement restrictions, either by embedding guardrails directly into the bill or by proposing amendments on the Senate floor.

Sources familiar with the matter indicated that Republicans were particularly focused on curtailing nearly $1.8 billion allocated for the "Anti-Weaponization Fund" and approximately $1 billion for the East Wing expansion of the White House. The "anti-weaponization" fund is a central component of a settlement between the Department of Justice and Trump concerning his $10 billion lawsuit against the IRS.

Details of the new bill remain undisclosed, making it unclear what specific restrictions Republicans aim to impose on the "anti-weaponization" fund. The fund is to be managed by a five-person commission appointed by the acting attorney general, with limited oversight beyond the president's power to remove commission members.

Republican Senator Susan Collins stated that Blanche's meeting did not alter her stance on the fund. Senator John Hoeven acknowledged that further discussions are necessary to build consensus, noting the current lack of a clear 50-vote majority for any specific configuration of the bill's provisions.

The situation highlights a significant internal division within the Republican party regarding the allocation of funds and the extent of presidential influence over such initiatives. The coming weeks will likely see continued debate and negotiation as Republicans attempt to reconcile their concerns before bringing the immigration bill back for consideration.
