John Walsh is leaving his position as a partner at WilmerHale while he explores unseating Sen. Cory Gardner in the U.S. Senate, according to an announcement from the firm. He hasn’t yet officially announced whether he is running.
Walsh joined the firm in 2017 after spending six years as U.S. Attorney for the District of Colorado and has served in the U.S. Attorney’s Office in Los Angeles, as well.
At WilmerHale, Walsh led the Denver office’s complex civil litigation, investigations and white collar criminal litigation team. He was recently named one of Law Week Colorado’s Top Litigators for 2019 for his work in receiving favorable settlements in high-profile cases involving DaVita and Anadarko as well as for his work in organizing the office’s pro bono efforts on behalf of immigrant detainees in the Aurora ICE detention center.
If he announces, he will run against Mike Johnston, who previously ran for governor of Colorado, and former Colorado House Speaker Andrew Romanoff in addition to Lorena Garcia, Keith Pottratz and Trish Zornio.
Walsh is the latest in a string of high-profile departures from WilmerHale’s Denver office in the last few months. Former Denver office co-partner in charge Natalie Hanlon-Leh left the firm to work as chief deputy attorney general in the Colorado Attorney General’s Office . Her counterpart, Andy Spielman, left the firm on a sabbatical recently, as well. The Denver office has also seen several associates join at the end of 2018, and Chalyse Robinson joined the firm in January as a partner as well. The office is currently being led by former U.S. senator and Interior Secretary Ken Salazar.
