Background

Jackson has served on the Supreme Court since 30 June 2022, nominated by President Joe Biden, and is the first Black woman to sit on it. Born in Washington DC in 1970, she clerked for Justice Stephen Breyer, whose seat she later filled. She worked as a federal public defender, served as vice-chair of the US Sentencing Commission, and was a judge on the federal district court in Washington and briefly on the D.C. Circuit.

In the 2026 election cycle she has been the liberal bloc's most visible voice on emergency applications. She dissented from the unsigned 2 June stay that let Alabama run its re-do primary on a contested congressional map.

As the justice WHO handles emergency applications from the First Circuit, she also acts alone. On 10 July she denied a federal stay in a Massachusetts ballot-access fight, the same day a state court restored Republican Michael Walsh to the attorney-general primary ballot.
