The U.S. government has been shut down for more than a month after Republicans and Democrats failed to agree on the 2026 fiscal budget. This second-longest shutdown in American history is causing widespread disruption to citizens and federal services alike.
The government can only reopen once both the House of Representatives and the Senate pass a funding bill. While Republicans have successfully passed it in the House with a simple majority, the real obstacle lies in the Senate, where despite holding a 53–47 majority, they cannot bypass the filibuster rule.
A filibuster allows senators to debate indefinitely, effectively blocking a bill unless 60 votes are reached to end debate. Because no single party usually holds that many seats, the rule gives the minority powerful leverage. Currently, Republicans would need to persuade seven Democratic senators to support the funding bill — an unlikely scenario.
By the end of October, the Senate had failed 13 times to approve temporary funding measures sent from the House. Facing the prolonged deadlock, President Trump called for invoking the “nuclear option,” allowing Republicans to pass the bill with a simple majority.
“It’s time for Republicans to play their trump card and go nuclear — end the filibuster now!” Trump wrote on Truth Social on October 30. “We’re in power. If we act, this ridiculous shutdown destroying our country will end immediately.”
To trigger the “nuclear option,” Senate Republican leaders would need to challenge the Parliamentarian’s interpretation of the rule. A simple majority of 51 votes could then override the filibuster, allowing the budget to pass — and setting a precedent for future legislative actions.
The idea is not new. In 2013, Democratic leader Harry Reid first invoked the “nuclear option” to bypass Republican filibusters on President Obama’s nominations. Republican leader Mitch McConnell warned at the time that it was a “dangerous, far-reaching change.”
In 2017, McConnell himself used the same tactic to remove the filibuster for Supreme Court nominations, paving the way for Trump to appoint three conservative justices.
Now, using it again to pass the budget could have lasting consequences. If Democrats regain control of the Senate, they could easily use the same precedent to push through tax hikes or sweeping policy reforms.
At least eight Republican senators have voiced opposition, meaning the “nuclear option” would likely fail even if brought to a vote.
“The filibuster forces us to find common ground,” Senator John Curtis said on October 31. “Power shifts, but principles should not. I strongly oppose abolishing it.”
Senate leader John Thune has also defended the rule, calling it “a shield against terrible ideas.” House Speaker Mike Johnson warned both parties need it equally:
“Abolishing the filibuster would open Pandora’s box,” Johnson said on C-SPAN. “If Democrats take back Congress, they could raise taxes to the ceiling and control everything.”
