Goldman Sachs' David Solomon will be one of two execs to replace Gary Cohn: Sources

David Solomon expected to fill Cohn's role at Goldman Sachs

David Solomon will be one of two people who is expected to fill the role of president and COO to replace Gary Cohn at Goldman Sachs, who will be leaving to join the administration of President-elect Donald Trump, sources told CNBC.

Solomon has served as the co-head of Goldman's Investment Banking Division since 2006. Prior to that, he worked as global head of the storied investment bank's Finance Group, which includes capital markets and derivative products for corporate clients, according to the firm's website.

The identity of the other individual who will move into the COO and president roles was not clear. It's not unusual for senior roles to be split at Goldman Sachs.

Cohn will leave Goldman to head Trump's National Economic Council. He will also serve as assistant to the president for economic policy, it was announced Monday.

Cohn "will help craft economic policies that will grow wages for our workers, stop the exodus of jobs overseas and create many great new opportunities for Americans who have been struggling," the president-elect said in a prepared statement from the presidential transition team.

Cohn joined Goldman in 1990. He worked previously for U.S. Steel and the New York Mercantile Exchange.
