Clinton emails search finds new message about Benghazi

A search of thousands of emails recovered during the FBI's investigation into Hillary Clinton's use of a private email server has produced one previously unreleased message related to the 2012 attack on a US diplomatic compound in Benghazi, Libya.

The message forwarded to Ms Clinton in January 2013 was from Tom Shannon, then-US ambassador to Brazil. The ambassador congratulated Ms Clinton on her testimony before the Senate Foreign Relations committee about the attack, during which four Americans died.
