the system works in a way that in order to keep those people who are willing to be the face of putin s regime like the ministers, they need to be incentivized. their salary is not enough. reporter: georgetown s jodie vitorri says the people in putin s inner circle know it could all vanish in an instant. he can turn on any of his regime any time he so chooses. your assets can be frozen, you going to jail, your family can go to jail, you can find yourself chased out. so moving as much as you can out of the country also makes sense. reporter: as for a response to this from the kremlin, a spokesperson from the ministry of foreign affairs tell us neither putin or lavrov have accounts in britain or anywhere else abroad. and as for the sanctions against putin s daughters a spokesperson told us this, that russia will respond without fail and will do so as it sees fit. drew griffin, cnn, atlanta.
