But until recently, Congress didn't have many Indigenous members who were pushing for solutions and funding for those issues. It's fueled by efforts to recruit Indigenous candidates and back them financially, get-out-the-vote efforts and Native communities flexing their political muscle. The U.S. Senate has not had a Native American member since Ben Nighthorse Campbell of Colorado retired in 2005. Most notably, it worked to pass two bills to help address the epidemic of missing and slain Native American women. Native Hawaiians are not among the more than 570 federally recognized Native American tribes, though they've sought the designation.
