On July 29, 2022, President Joe Biden announced his intent to nominate Kobick to serve as a United States district judge of the United States District Court for the District of Massachusetts.[3] On August 1, 2022, her nomination was sent to the Senate. President Biden nominated Kobick to the seat vacated by Judge William G. Young, who assumed senior status on July 1, 2021.[12] On November 30, 2022, a hearing on her nomination was held before the Senate Judiciary Committee.[13] During her hearing, she was repeatedly questioned by Senator Josh Hawley about an argument she made before the Supreme Court, claiming the Second Amendment did not apply to stun guns because they did not exist when the Amendment was written; an argument which had previously been rejected unanimously by the Court, and which the Court again rejected when she made it.[14] On January 3, 2023, her nomination was returned to the President under Rule XXXI, Paragraph 6 of the United States Senate. She was renominated on January 23, 2023.[15] On February 9, 2023, her nomination was reported out of committee by an 11–10 vote.[16] On November 7, 2023, the Senate invoked cloture on her nomination by a 52–46 vote, with Senator Joe Manchin voting against the motion to invoke cloture on her nomination.[17] Later that day, Kobick was confirmed by a 52–46 vote, with Senator Manchin voting against confirmation.[18] Kobick's confirmation made her the 150th judge confirmed during the Biden presidency.[19][20] She received her judicial commission on November 13, 2023.[21]
