Former City Comptroller and current congressional candidate Brad Lander oversaw a major expansion of New York City public pension fund investments in Palantir Technologies, a data analytics firm whose software has long been used by Immigration and Customs Enforcement (ICE) to identify and deport undocumented immigrants. During Lander's tenure as the city's chief financial officer, the city's five public pension funds significantly increased their exposure to Palantir, according to an amNewYork review of pension fund disclosures.
