John Walsh, the former U.S. attorney for Colorado and Wilmer Cutler Pickering Hale and Dorr partner who in April announced a 2020 U.S. Senate run in Colorado, returned to his old firm this week after bowing out of the senate race in September, Wilmer said Wednesday.

When Walsh embarked on his campaign in April, he said he was unsure whether he would return to Wilmer if his campaign failed to take off, saying, “Right now, the focus is on winning.”
