U.S. Attorney Dwight Holton also entered the race, and held an early fundraising advantage with the support of most of the state's law enforcement community. Rosenblum focused on social issues, and when Holton criticized the Oregon Medical Marijuana Act, Rosenblum gained the support of Oregon marijuana legalization supporters by pledging to "make marijuana enforcement a low priority, and protect the rights of medical marijuana patients."

In July 2020, Rosenblum filed a lawsuit against the federal government, accusing it of unlawfully detaining protesters, after footage emerged of agents in unmarked vehicles appearing to forcefully seize protesters without justification.
