In a shift, Trump now aligns more closely with Putin than allies in Europe in calling for final talks before a ceasefire

The Alaska summit between the U.S. and Russian leaders showcased their mutual animosity for the former president.

Oil prices slipped on Monday as the U.S. did not exert more pressure on Russia to end the Ukraine war by implementing further measures to disrupt Russian oil exports after the presidents from both countries met on Friday.

The highly anticipated summit ended without a breakthrough. Afterwards, Trump said Ukraine and Russia should proceed straight to seeking a full peace deal instead of a cease-fire.

President Trump visits Alaska Friday for a meeting with Russia's President Vladimir Putin — a discussion the White House has called a "listening exercise."

It is quite possible that Monday's meeting in the White House could prove even more crucial to the future of Ukraine - and for all of Europe's security - than last Friday's US-Russia summit in Alaska. On the surface, that Putin-Trump reunion seemed to live down to every expectation. There was no ceasefire, no sanctions, no grand announcements.

President Donald Trump said progress had been made in Friday's Alaska summit with the Russian leader, but no deal on peace in Ukraine has been reached.

European leaders will join Volodymyr Zelenskiy to meet Donald Trump in Washington, they said on Sunday, seeking to shore up Zelenskiy's position as the U.S. president presses Ukraine to accept a quick peace deal to end Europe's deadliest war in 80 years.
