Former New York Mayor Michael Bloomberg is interested in serving as secretary of state under Hillary Clinton, according to emails published by WikiLeaks, but views the prospect as unlikely.

“Is there something Mike Bloomberg would want to do in his life in an Admin? Is like Ambassador to China way too small?” Neera Tanden, a co-chair on Clinton’s presidential transition team, wrote in a June 2015 email to Howard Wolfson, an aide to Bloomberg.
