What Happens If Justice Samuel Alito Retires from the Supreme Court?
What Happens If Justice Alito Retires from Supreme Court?

Washington is abuzz with speculation that President Donald Trump might nominate one or more Supreme Court justices before the November midterm elections. In a Fox Business interview on April 15, 2026, Trump discussed the potential retirement of Justice Samuel Alito, 76, a reliably conservative justice appointed by President George W. Bush in 2005. Trump praised Alito as 'a great justice' and indicated readiness to appoint a replacement if Alito steps down. Trump added, 'In theory, it's two – you just read the statistics – it could be two, could be three, could be one.' He did not specify other potential retirees, but pundits speculate Justice Clarence Thomas, 77, another solid conservative vote, might be among them. Thomas, appointed by George H.W. Bush in 1991, is the court's oldest and longest-serving justice.

Context and Timing

In the same interview, Trump referenced former Justice Ruth Bader Ginsburg, who faced pressure to retire during President Barack Obama's presidency but chose to stay, dying in September 2020. Republicans had blocked Obama's appointment of Merrick Garland in 2016 after Justice Antonin Scalia's death. In 2020, Trump replaced Ginsburg with Justice Amy Coney Barrett, solidifying a 6-3 conservative majority. As a scholar of the Supreme Court confirmation process, I note that Trump's comments are closely tied to the November midterms. If Democrats take the Senate, they would likely block a Trump nominee, following the 2020 Republican precedent. The clock is ticking, and Democrats' chances of retaking the Senate are improving. Assuming a justice retires, here's what must happen for Trump and Senate Republicans to confirm a successor.

The Supreme Court Confirmation Process

The Constitution grants the Senate 'advice and consent' on Supreme Court appointments. Over history, this has evolved into a complex procedure. Once the president nominates someone, the nomination goes to the Judiciary Committee. There, confirmation hearings occur, typically lasting three to four days, featuring high-stakes questioning of the nominee. Before hearings, senators and nominees engage in extensive preparation. Senators conduct background research, partly through the Senate Judiciary Committee questionnaire, to which nominees provide written answers. For example, Justice Ketanji Brown Jackson's 2022 questionnaire was 149 pages, covering organizational memberships, public speeches, and judicial opinions. Meanwhile, nominees make courtesy calls to senators to build support.

Preparation and Hearings

Around the same time, nominees participate in 'murder boards,' where allies play Judiciary Committee members, anticipating tough questions from opposition senators. During Jackson's murder boards, the focus was on expected Republican attacks that she was soft on crime. After hearings, the Judiciary Committee votes on its recommendation to the full Senate. The nomination then goes to the full Senate for debate and a final confirmation vote, requiring a simple majority. On average, it takes 70 days from appointment to confirmation, but recent confirmations have been faster: Barrett took 30 days, Jackson 41. Thus, with roughly a month before the midterms, there is likely enough time for the Republican Senate to confirm a Trump nominee.

Democrats' Limited Options

In 2017, Senate Republicans ended the filibuster for Supreme Court nominees to secure Neil Gorsuch's confirmation, reducing the threshold from 60 to 51 votes. This severely limited minority party options to block a confirmation. With a 53-47 Republican majority, if Republicans stay united, Democrats will find it very difficult to block a Trump nominee. Some delay tactics exist—Democrats could grind the Senate to a halt—but they may face political costs. Republicans might paint Democrats as obstructionist, potentially motivating voter backlash in the midterms. Nonetheless, Democrats may view this as a fight worth having, as confirming another Republican-appointed justice would ensure conservative dominance on the court for decades to come.
