Biden targets the daughters of Russian President Vladimir Putin in the White House’s latest round of sanctions. Putin’s two daughters, Katerina Vladimirovna Tikhonova and Maria Vladimirovna Vorontsova are suspected by the United States authorities to be hiding their father’s wealth.

“We have reason to believe that Putin, and many of his cronies, and the oligarchs, hide their wealth, hide their assets, with family members that place their assets and their wealth in the US financial system, and also many other parts of the world,” a senior Biden administration official said in a statement to reporters.

Sanctions announced last Wednesday also included Russian Foreign Minister Sergey Lavrov’s daughter and wife, members of the Russian Security Council, former President and Prime Minister of Russia Dmitry Medvedev, and Prime Minister Mikhail Mishustin.

“We believe that many of Putin’s assets are hidden with family members, and that’s why we’re targeting them,” the official said, speaking on the condition of anonymity.
