Liberal-leaning legal groups were busy in court during the Trump administration—and the new leader of one of those organizations said that work won’t end anytime soon.

Skye Perryman, a former Big Law attorney and one of the founding litigators for the group Democracy Forward, rejoined the organization this month as its president and CEO. The group was founded in 2017 and has since filed hundreds of legal challenges, often teaming up with other groups or law firms for the work.
