Did Secret Payments Secure Kyrgyz Military Base?

From Laura Rozen:

As the Kyrgyz Republic threatens to kick the United States out of its Manas air base, which it has been using as a major logistics and supply point into Afghanistan, sources familiar with developments say the back story has to do with payments the United States previously made that did not make it into the Bishkek government’s coffers, but rather, to subcontractors controlled by the family of the previous ruler Askar Akayev.
