Kenneth Wainstein, one of Washington, D.C.'s top white-collar lawyers, is jumping firms.

Wainstein is leaving Cadwalader, Wickersham & Taft, where he was co-chair of the firm's litigation department and chair of the white-collar group, for another Wall Street mainstay, Davis Polk & Wardwell.

The move coincides with one of the hottest stretches Washington's white-collar bar has experienced in years. As federal investigations plague the Trump administration, Wainstein has been among the prominent lawyers circling the action.
