President Barack Obama actually did know that Hillary Clinton used a non-government email address when she was secretary of state, but didn’t know the extent of her private email system, White House spokesman Josh Earnest said Monday.
“I would not describe the numbers of emails as large. … He was not aware of the details of how that email address and that server had been set up,” Earnest said.
That’s a shift from Saturday, March 7, when Obama told CBS that he learned about Clinton’s private email system in the news.
