U.S. President Joe Biden said on Friday that Russian referendums aimed at annexing four occupied regions of Ukraine are a sham and said Washington "will never recognize Ukrainian territory as anything other than part of Ukraine."
In a statement, Biden said Washington "will work with our allies and partners to impose additional swift and severe economic costs on Russia."
