this is the beginning of a russian invasion of ukraine, and hitting back at vladimir putin with sanctions on two russian banks with more than $80 billion in assets as well as some of the country's wealthiest elites and their families. and warning, that's not all. >> if russia goes further with this invasion, we stand prepared to go further as with sanctions. who in the lord's name does putin think gives him the right to declare new so-called countries on territory that belonged to his neighbors? this is a flagrant violation of international law. and demands a firm response from international community. >> a senior administration official saying the sanctions are, and i quote here, only the sharp edge of the pain we can inflict, and calling the two banks, quote, a glorified piggy bank for the kremlin. these are tough sanctions, but are they tough enough? will anything stop vladimir putin? another tough question.
