In one of the largest mass lateral moves between two Am Law 100 firms in recent months, 10 partners have left K&L Gates in Washington, D.C., for rival Mayer Brown.

The moves cut deeply into K&L Gates’ consumer credit compliance and enforcement practice, which had already lost five partners to Mayer Brown earlier this month. Factoring in 15 associates, a counsel and a staff attorney who are also making the jump, 32 K&L Gates lawyers have now left for Mayer Brown, including 24 in Washington, two in Palo Alto, California, and one in Houston.
