Sergeant at Arms of the United States Senate
On January 7, 2021, Hemingway was named by Senate Majority leader Mitch McConnell as acting Senate Sergeant at Arms, following the resignation of Michael C. Stenger after the 2021 storming of the United States Capitol. House sergeant-at-arms Paul D. Irving and United States Capitol Police chief Steven Sund also resigned the same day, amid bipartisan shock and outrage over security lapses that led to the mob's breach and occupation of the Capitol. She held the post until General Karen Gibson was confirmed as the new Senate Sergeant at Arms.
