Ukraine crisis: Meet the Indian American who is leading Joe Biden's economic assault on Russia

Meet the man leading the Joe Biden administration's economic offensive against Russia amid the Ukraine crisis.

Economic advisor Daleep Singh is leading the efforts of the Biden administration to impose punitive sanctions on Russia over its actions against Ukraine.

Singh, who is Deputy National Security Advisor for international economics and Deputy Director of the National Economic Council, made his second appearance in the White House Press Room in a matter of days.

White House Press Secretary Jen Psaki said that he is "back by popular demand" given the key role Singh is playing in this Russia policy of the administration.

As the Biden administration and the West clamped a series of sanction on Russia, Singh said this was the beginning of an invasion and this was the beginning of the American response.

"Russia's long previewed invasion of Ukraine has begun and so too has our response. Today, the president (Joe Biden) responded swiftly and in lockstep with allies and partners. The speed and coordination were historic... It took weeks and months to mount a decisive response," Singh told reporters in his opening remarks.
