On May 17, 2019, Austin publicly admitted that she had hired family members as interns on her committee payroll, refusing to apologize for it.[3] The same day, mayor-elect Lightfoot announced that she would be naming Pat Dowell to supplant Austin as the City Council's budget chairman.[3] Austin publicly took offense to this move by Lightfoot.[3]
On July 1, 2021, Austin was indicted for allegedly taking bribes from a private development firm.[6]
