Kirkland & Ellis added another former Morrison & Foerster lawyer, Ali Zaidi, to its corporate practice in Washington, D.C., this week.

Zaidi, who joins Kirkland as of counsel, focuses on environmental risks and regulatory hurdles arising in M&A deals. In leaving MoFo for Kirkland, he’s following a path beat just last month by partner Robert Fleishman, who specializes in defending energy and financial industry clients in regulatory enforcement matters.
