“We wish her a speedy recovery as she seeks the appropriate medical treatment that she has long needed and sought,” the White House said in a statement issued on Saturday.
“The unshakeable principle guiding events must be that the people of Ukraine determine their own future,” the statement added.
Earlier in the day, Tymoshenko was released from the hospital where she had been held under prison guard in the northeastern city of Kharkiv after the Ukrainian parliament voted to free her.
Ukraine has been rocked by anti-government protests after President Viktor Yanukovich refrained from signing the Association Agreement with the European Union at the third Eastern Partnership Summit in the Lithuanian capital Vilnius on November 29, 2013.
According to the country’s Health Ministry, at least 77 people, including police officers, have died since the latest round of violence broke out on Tuesday.
However, Ukraine’s opposition places the toll much higher, saying that at least 100 protesters died just on Thursday in clashes with police.
“We have consistently advocated a de-escalation of violence, constitutional change, a coalition government, and early elections, and today’s developments could move us closer to that goal,” the White House said.
“We welcome constructive work in the Rada (parliament) and continue to urge the prompt formation of a broad, technocratic government of national unity,” it added.
“We will work with our allies, with Russia, and with appropriate European and international organizations to support a strong, prosperous, unified, and democratic Ukraine,” the statement noted.
