From 2022 to 2024, Rush was an Associate Deputy Attorney General, serving as one of the most senior counselors to Attorney General Merrick Garland and Deputy Attorney General Lisa Monaco. His responsibilities covered the DOJ’s most consequential and sensitive decisions, including oversight of multiple special counsel investigations, the DOJ’s efforts against the Russian invasion of Ukraine and the DOJ’s January 6 prosecutions.

Rush co-chaired the DOJ’s Corporate Crime Advisory Group, which developed significant revisions to policies governing the prosecution of white collar crime, deferred and non-prosecution agreements, voluntary self-disclosure programs and the use of corporate monitors. Rush was also central to the DOJ’s focus on the intersection of white collar matters and national security, including corporate accountability for sanctions, export control, money laundering and Bank Secrecy Act violations.

Rush separately oversaw the development of new cyber capabilities for the Department, including new units dedicated to investigating and prosecuting federal crimes involving cryptocurrency, ransomware and state-sponsored hacking.

In 2020, Rush led the DOJ’s criminal investigations into COVID-19 fraud.   From 2017 to 2019, Rush served as an Assistant Special Counsel investigating cyber and social media interference in U.S. affairs by foreign actors. Previously, as a federal prosecutor and Assistant Chief in the DOJ’s Fraud Section, Rush prosecuted high-profile corporate matters involving market manipulation in foreign exchange markets, securities fraud by public corporate executives, insider trading, FCPA violations, healthcare fraud and other white collar matters. He handled five federal criminal jury trials and supervised dozens of others.
