Supreme Court justices Ketanji Brown Jackson and Brett Kavanaugh sparred publicly on Monday over how the court has repeatedly stepped in to aid policies pushed by President Donald Trump.

The rare exchange occurred during a joint appearance at a federal courthouse event in Washington, D.C., where the two justices discussed the court’s growing use of emergency rulings – often referred to as the “shadow docket,” according to NBC News.

Liberal Supreme Court Justice Ketanji Brown Jackson warned last summer that her conservative colleagues on the bench were doing irreparable harm to the court’s image as they increasingly sided with the rich and powerful, and a new study published Monday appeared to validate those fears.

Published by the National Bureau of Economic Research, the study found that since the 1950s, conservative Supreme Court justices increasingly issued rulings that favored the wealthy when compared to their liberal counterparts.

Supreme Court Justices Ketanji Brown Jackson and Brett Kavanaugh engaged in a rare public debate Monday over the court's expanded use of emergency rulings, known as the "shadow docket," to advance Trump administration policies. Jackson criticized the conservative majority's willingness to intervene early in legal challenges, calling the uptick "a real unfortunate problem" that creates "a warped kind of proceeding." She warned the practice signals lower courts how the Supreme Court might ultimately rule and "is not serving the court or this country well," remarks that drew applause from a packed audience including lower court judges. Kavanaugh defended the court's actions, arguing justices must respond to government emergency applications and noting similar requests came from prior administrations. The public exchange marked a rare moment of justices debating internal court business openly, moving beyond written opinion disagreements.

A far-right U.S. senator is demanding that Chief Justice John Roberts open a Supreme Court investigation into Justice Ketanji Brown Jackson's attendance of the Grammy Awards, Newsweek reported.

"Senior U.S. Senator Marsha Blackburn of Tennessee said Jackson should be looked into, as the awards ceremony was rife with remarks opposing U.S. Immigration and Customs Enforcement (ICE), while some critics have accused Jackson of clapping during those moments," said the report. "While there is no proof that Jackson clapped at any of the anti-ICE comments while in attendance at the Grammys, Blackburn wrote a letter urging Roberts to look into the matter."

Chief Justice John Roberts moved aggressively this week to rein in Justices Sonia Sotomayor and Ketanji Brown Jackson during Supreme Court oral arguments, repeatedly cutting off the liberal justices as their questioning frustrated colleagues and sparked conservative outcry online.

The tensions came to a head during arguments over mail-in ballots and asylum policy enforcement, with Roberts intervening multiple times to enforce courtroom decorum, reported The Hill's Ella Lee and Zach Schonfeld.
