Monday’s face-to-face between the two leaders looked markedly different.

On a day of deep diplomatic intrigue and the biggest of geopolitical questions, it was a sartorial matter that was settled first at the White House.

Mr Glenn, a Real America’s Voice host, apologised to the Ukrainian president for his earlier jibe during the recent encounter.

Zelenskyy said the Washington talks with the US president and European leaders were "truly a significant step toward ending the war and ensuring the security of Ukraine and our people".

Russia had agreed to allow the US and Europe to give Ukraine "robust" security guarantees as part of a potential peace deal.

Trump pledged U.S. help to protect Ukraine in a cordial sit-down with Zelenskyy.

Here are some key takeaways from the high-stakes meeting. President Trump on Monday said the United States will be involved in security assistance for Ukraine -- a key condition for Zelenskyy in any deal to end the war -- but did not elaborate on what exactly that would look like or give any specifics.

U.S. President Donald Trump expressed hope that Monday's summit could eventually lead to a trilateral meeting with Russian President Vladimir Putin, adding that he believes Putin wants the war to end.

“There’s going to be a lot of help,” Mr Trump said. “They are first line of defence because they’re there. They’re Europe. But we’re going to help them out also. We’ll be involved.”
