President-elect Joe Biden’s pick for undersecretary of defense for policy, Colin Kahl, has a long history of perpetuating Russian disinformation. On Wednesday, Biden made the announcement that Kahl would be joining the administration after serving as a deputy assistant to President Barack Obama and national security adviser to Vice President Biden from 2014 to 2017. Kahl is currently co-director at the Stanford Center for International Security and Cooperation and a strategic adviser at the Penn Biden Center. “I know how hard the professionals in Policy work every day to keep America safe,” Kahl wrote on Twitter in response to the appointment. “I would be honored to lead this great organization.”
