With Britain’s vote to leave the European Union, U.S. President-elect Donald Trump’s campaign promises to “rip up” free trade agreements and nationalist movements gaining ground in other European countries, Baker & McKenzie’s new chairman is leading a firm known for cross-border dealmaking as protectionist rhetoric threatens to scuttle international cooperation and trade.

Baker & McKenzie’s 15th global chairman Paul Rawlinson has been on a tour of his firm’s North American offices in recent days. He’s been to Seattle, Los Angeles, Dallas and on Friday he was in Chicago, where the firm got its start in 1949.
