Silicon Valley-based Wilson Sonsini Goodrich & Rosati, which has been focused on growth in the nation’s capital, has now hired longtime O’Melveny & Myers partner Kenneth O’Rourke to bolster its antitrust litigation practice.

O’Rourke is the sixth partner Wilson Sonsini has added to its Washington, D.C., office this year. He previously practiced in California, and plans to split his time between Washington and the West Coast.
