John Clune, an attorney at the Colorado-based firm Hutchinson Black and Cook, is representing Deborah Ramirez, the former Yale classmate of Brett Kavanaugh who is accusing the Supreme Court nominee of sexually inappropriate behavior in college.

Clune stepped in as Stanley L. Garnett, a shareholder at the Denver-based law and lobbying firm Brownstein Hyatt Farber Schreck, has transitioned out of his role representing Ramirez, a spokeswoman at Brownstein Hyatt confirmed.

The development comes as a lawyer for Senate Judiciary Committee Chairman Chuck Grassley, R-Iowa, reached out to Garnett on Sunday night, according to a Grassley aide. The lawyer asked for Ramirez's availability for an interview with the committee's investigators.
