Speculation is swirling that Supreme Court Justice Anthony Kennedy could announce his retirement as early as this term, The Associated Press and CNN reported Saturday.

Kennedy is considered the most pivotal justice on the Supreme Court, often known for casting the tie-breaking vote in key decisions.

While he's among the court's conservative justices, he has sided with his liberal colleagues at times, including on the court's 2015 decision in Obergefell v. Hodges, permitting same-sex marriage nationwide.

But Kennedy, now 80, is said to be considering stepping down from the Supreme Court, according to CNN, though he has not publicly signalled he will do so in the next year.

Fueling such speculation is a reunion between Kennedy and his clerks happening over the weekend that was pushed up a year from its original date, according to the AP.
