The Senate has approved President Trump’s nomination of Allison Herren Lee to a seat on the Securities and Exchange Commission.

The former aide to Commissioner Kara Stein hails from Colorado.

Lee, a Democrat, fills the seat already vacated by Stein, restoring the five-member Commission to full strength. She will serve a five-year term that expires on June 5, 2022.

A veteran securities law practitioner for more than two decades, Lee served at the SEC from 2005 to 2018 in various roles, including senior counsel in the Complex Financial Instruments Unit and as counsel to Stein. The latter position helped fuel what were ultimately spot-on prognostications of her eventual nomination.

Lee has also served as a special assistant U.S. attorney and, prior to government service, was a litigation partner at the law firm Sherman & Howard in Denver.

For one year starting in 1997, she was law clerk to Judge Love Kourlis of the Colorado Supreme Court. She earned her law degree from the University of Denver’s Sturm College of Law.

Since leaving the SEC, Lee had lectured and taught courses in financial regulation and corporate law at Universidad de Navarra in Pamplona, Spain, and LUISS Universita Guido Carli, Dipartimento di Giurisprudenza in Rome, Italy.
