U.S. Attorney for the District of South Dakota
Johnson was nominated by President
Barack Obama as the 40th
United States Attorney for the District of South Dakota and was unanimously confirmed by the United States Senate on October 15, 2009. He stepped down from the position on March 13, 2015. His nomination to be United States Attorney was supported by several prominent
Republicans, including former Governor
Bill Janklow, former State Attorney General
Larry Long, former
Sioux Falls Mayor
Dave Munson, and a variety of state and local law enforcement leaders. In 2009, the Attorney General of the United States selected Johnson to serve as chairman of the Native American Issues Subcommittee. Two years later the Attorney General selected Johnson to serve on the Attorney's General Advisory Committee. Johnson is a member of the Terrorism and National Security Subcommittee. As South Dakota's chief federal law enforcement officer, Johnson's office prosecuted several high-profile child exploitation cases, including the case of an individual who received a life sentence for the human trafficking of minors. He also convened the first statewide Tribal Listening Session, a statewide civil rights conference, and has been an outspoken advocate on violence against women issues.
Native American issues Johnson increased his office's focus on Native American issues. He worked the night shift with tribal police officers, conducted leadership training for Native American youth, and implemented a new statewide community based prosecution strategy. His focus resulted in an increase in prosecutions. Some of his office's high-profile prosecutions include a 17-person drug conspiracy in Pine Ridge known as Operation Prairie Thunder. Johnson and his counterpart in North Dakota, former U.S. Attorney
Tim Purdon, were known as the “Dakota Boys” within the Justice Department and together they focused on improving public safety in tribal communities across the country.
Richard Hartunian, U.S. Attorney for the Northern District of New York, said
"the efforts of the Dakota Boys were a turning point in U.S.-Tribal relations ... Brendan and Tim were the right leaders at the right time to carry out the vision of President Obama and Attorney General Holder to improve public safety in Indian Country". Purdon and Johnson joined the law firm of Robins Kaplan LLP together and now work together on behalf of tribes in private practice.
Human trafficking As United States Attorney, Johnson oversaw the prosecution of more than 25
human trafficking cases in five years, including three life-sentences and the federal prosecution of numerous men who attempted to purchase sex from trafficking victims. He pursued the case of United States v. Jungers through the Eighth Circuit Court of Appeals, securing the critical decision that buyers of sex acts with minors are committing crimes of sex trafficking under the federal law, upping the risk of such activity by those who drive the sex trafficking markets. In 2014, Johnson received Shared Hope International's Pathbreaker Award for determined leadership in combatting child sex trafficking: “Brendan Johnson is a force of determination, initiative and skill that should leave buyers terrified to purchase sex with a minor in South Dakota,” Shared Hope International President and Founder Linda Smith said. “By creating a threshold for buyer accountability, he sets a national precedent that, if applied, will make significant strides in reducing tolerance for purchasing sex with a minor.” ==Later legal career==
