US President Donald Trump has said he is ready to assume commitments regarding US participation in future security guarantees for Ukraine because he believes that Russia will not attempt another invasion.

Ronald S. Lauder, a billionaire friend of Mr. Trump, is among the investors. The move comes as the Trump administration looks for investment opportunities in Ukraine.

President Trump refuted the Kremlin’s accusations that Ukraine targeted a residence of Russian strongman Vladimir Putin, doubting such an attack ever took place.

A CIA assessment concluded that Ukraine didn't try to kill Russian President Vladimir Putin at his country residence as alleged by the Kremlin, a source with knowledge of the matter told NBC News last week.

President Trump indicated that he was ready to commit to the United States being involved in Ukraine’s future defense — but only, he said, because he was confident that Russia would not try to invade the country again.

Russian officials indicated in 2019 that the Kremlin would be willing to back off from its support for Nicolás Maduro in Venezuela in exchange for a free hand in Ukraine, according to Fiona Hill, an adviser to President Donald Trump at the time.

Fiona Hill said Russian officials had suggested a "swap arrangement" based on the principles of the Monroe Doctrine.

President Trump's advisers Steve Witkoff and Jared Kushner met Wednesday in Paris with Russian envoy Kirill Dmitriev to discuss the U.S. plan for peace in Ukraine, according to a source with knowledge.
