with president karzai while he's there? >> reporter: we don't have any reports about that right now. as you know the obama administration's relationship with president karzai has been quite strained because karzai has refused to sign the security agreement which would essentially have set those troop levels. the administration is hoping the next president who takes over in afghanistan will do that. there's no reports president obama is planning to meet with president karzai, but i wouldn't rule this out. he just landed in afghanistan. the white house has to keep these types of things under wraps because of the president's security, of course, that being of the utmost concern. this is something we have seen this president do in the past and president george w. bush visited with troops in afghanistan. made a surprise visit.
