The White House says the administration "is not waiting" to take action against Russia for its aggression toward Ukraine and announced sanctions against four Ukranian officials accused of helping Moscow. Speaking at the briefing Thursday, White House press secretary Jen Psaki said the latest sanctions are "part of our ongoing longstanding efforts to counter Russia's network of influence efforts and to expose Russia's dangerous, threatening and ongoing campaign to destabilize Ukraine." The sanctions name Ukrainian parliament members Taras Kozak and Oleh Voloshyn and two former government officials. According to Treasury, all four have been intimately involved in disinformation efforts by Russia's federal security service, known as the FSB. The announcement comes less than 24 hours after President Joe Biden said he thinks Moscow will newly invade Ukraine.
