U.S. Senators Cory Booker (D-NJ), Ron Wyden, (D-OR), Sherrod Brown, (D-OH), Edward Markey, (D-MA), and Kamala Harris, (D-CA), and U.S. Representatives Yvette Clarke, (D-NY), Ayanna Pressley, (D-MA), and Rashida Tlaib, (D-MI), asked the U.S. Department of Housing and Urban Development (HUD) to review policies regarding the use of facial recognition technologies in federally assisted housing.In a letter to HUD Secretary Ben Carson, the lawmakers pointed out the threats that facial recognition technology pose to marginalized communities, opening the door to unchecked government surveillance.”[HUD] is responsible for creating and ensuring discrimination-free practices in all communities,” the lawmakers wrote. “However, as numerous civil rights experts have pointed out, when public housing and federally assisted property owners install facial recognition security camera systems, they could be used to enable invasive, unnecessary and harmful government surveillance of their residents. Those who cannot afford more do not deserve less in basic privacy and protections. They should not have to compromise their civil rights and liberties nor accept the condition of indiscriminate, sweeping government surveillance to find an affordable place to live.”Experts have also noted inaccuracies in facial recognition technology that disproportionately affect marginalized communities .”These false and biased judgments can exacerbate the vulnerabilities that marginalized groups already face in life, such as the overcriminalization of people of color and transgender individuals. Potential sharing of this data, particularly with law enforcement, further heightens concerns about the risk this technology poses to vulnerable communities,” the lawmakers continued.The lawmakers requested a response from HUD by January 24, 2020.

With this proposed rule, HUD, the nation's main civil rights enforcer for housing discrimination, effectively provides a road map for landlords and lenders who wish to discriminate by algorithm.Booker and Wyden authored the Algorithmic Accountability Act , which requires companies to fix discriminatory algorithms and outlines methods the federal government can use to mitigate the impacts of such algorithms.Last year, Booker secured a commitment from Facebook CEO Mark Zuckerberg — for the first time — to conduct a civil rights audit that, among other items, would address the algorithmic biases on its platforms. Also last year, he secured language in the Federal Aviation Administration Authorization Act requiring TSA to report to Congress on methods to eliminate bias on race, gender, and age as it begins deploying facial recognition on domestic flights.
