Ukraine is benefiting from Donald Trump's frustration with Vladimir Putin, but his first six months in office show that no one knows if it will last.

Trump said he would end the war in Ukraine within his first 24 hours in office. His patience with Russia's Putin now appears to be wearing thin.

A bipartisan U.S. bill that would hit Russia with sanctions in a bid to pressure Moscow into good-faith peace negotiations with Ukraine has gained momentum this week in Congress, but it still lacks the presidential push it needs to get over the finish line.

A detailed timeline of events shows the White House was aware of an ordered pause in weapons to Ukraine in real time and Trump's decision to reverse the action.

The arrangement allows Ukraine to get weapons it needs in its war with Russia while providing a way for Europe to increase its defense spending as promised.

President Donald Trump could send as much as $300 million in military aid to Ukraine, one source told Reuters.

A new book alleges that President Donald Trump told donors he threatened Russian President Vladimir Putin with bombing Moscow if Russia invaded Ukraine.
