First Lady Michelle Obama made her first visit to the Late Show with David Letterman on Monday night, dishing on her private conversations with the President.
As a married man, Dave knows about the talks that husbands and wives have behind closed doors. The talk show host was curious to find out if President Obama's measured disposition slips away when discussing problems at work.
"He is always upbeat, particularly about Congress," the First Lady joked.
