CBS News reported the information.A U.S. official confirmed on Tuesday that Ukraine's government had agreed to a peace deal facilitated by the Trump administration, with Ukrainian National Security Adviser Rustem Umerov expressing hope that President Volodymyr Zelenskyy could travel to Washington before the end of November to finalize the arrangement."The Ukrainians have agreed to the peace deal," the U.S. official said. "There are some minor details to be sorted out but they have agreed to a peace deal."The development coincided with U.S. Army Secretary Dan Driscoll's presence in Abu Dhabi, where he spent hours Tuesday negotiating with Russian representatives, according to multiple U.S. officials and diplomatic sources. A U.S. military official on the ground described the atmosphere as optimistic, noting that Driscoll moved between meetings throughout the day."We remain very optimistic," the official said. "Secretary Driscoll is optimistic. Hopefully, we'll get feedback from the Russians soon. This is moving quick."White House press secretary Karoline Leavitt wrote on social media Tuesday morning that "the United States has made tremendous progress towards a peace deal by bringing both Ukraine and Russia to the table," adding that "a few delicate, but not insurmountable, details" still need to be resolved.Umerov stated that Ukraine had reached "a common understanding on the core terms" following discussions among U.S., European and Ukrainian officials in Geneva over the weekend. "We now count on the support of our European partners in our further steps," he said, expressing eagerness to arrange Zelenskyy's visit to complete the deal with President Trump.Russia's response remained notably absent. Foreign Minister Sergey Lavrov told reporters that while Moscow "appreciates the U.S.' position," Russia "operates professionally, not leaking information before formal agreements are reached." He said Russia expects the U.S. to share results of consultations with Ukraine and Europe "in the near future."The negotiations in Abu Dhabi involve U.S., Ukrainian and Russian officials, though not all meeting simultaneously. A source with knowledge of the talks indicated that Driscoll was working from a revised version of the White House's 28-point proposal following productive Geneva negotiations.Last week's draft proposal included provisions Zelenskyy has previously rejected, such as requiring Ukraine to cede its entire Donetsk region and abandoning NATO membership aspirations. However, an accompanying document on security guarantees reportedly offers assurances similar to NATO's Article 5 mutual defense commitment, according to Ukraine's U.S. Ambassador Olha Stefanishyna.President Trump has pressed for a deal by Thanksgiving, though Secretary of State Marco Rubio described that deadline as flexible. A U.S. official noted that Russian leader Vladimir Putin appears convinced he will secure Donetsk either through negotiation or continued fighting, with the Trump administration's approach acknowledging this reality.
