Clinton is soon to leave her post as secretary of state, and already she is being mentioned as a possible presidential candidate for 2016.

Obama and Clinton competed for the Democratic nomination for president in 2008, and their relationship has been watched closely ever since.

It's not clear what questions the two will face in their joint interview.

Clinton wearing glasses due to concussion

Hillary Rodham Clinton's thick-framed glasses aren't just a style statement.

Spokesman Philippe Reines says the secretary of state will be wearing the glasses instead of contacts for a period of time because of lingering issues stemming from a concussion she suffered in December.

The dark glasses with rectangular lenses have been conspicuously present since Clinton returned to work this month.

Reines gave no details on what types of lenses she is using

But he insisted Friday that with them on, Clinton sees "just fine."

He said Clinton has enjoyed reading humorous articles interpreting what each adjustment of her glasses means.
