US Republicans push for more European involvement
One US Republican senator tells the BBC that he believes "we need to continue" supporting Ukraine, "but I think it's even more important for Europe to step up and contribute more".
Speaking to the BBC's state department correspondent Tom Bateman, Senator John Cornyn says "Russia clearly can't be trusted" and he is "sceptical of any promises" its President, Vladimir Putin, makes.
"That's why we need some sort of backup plan, hopefully led by the Europeans, but supported by the United States."
That need for European involvement is reiterated by Senator Rick Scott.
"Russia is the aggressor... Ukraine needs to win", he says, but "the Europeans are going to have start standing up" in their defence of the country."
"You can't expect American taxpayers... to do all this", he adds.
'Unacceptable', 'a betrayal' - US Democrats react to Ukraine aid cuts
Democratic lawmakers in the US have slated the decision to suspend military assistance - and intelligence sharing - with Ukraine.
Senator Cory Booker tells the BBC's state department correspondent Tom Bateman that he had not heard the reports of a halt to intelligence sharing with Ukraine "but that would be unacceptable to me, and pretty outrageous".
He adds that the stopping of military aid is a "betrayal of Congress's intent", since it has already approved funds for Ukraine.
Senator Tim Kaine calls it "a huge mistake". "This secession of aid, military aid that Congress has appropriated, I think, is illegal," he adds.
This is something Democrats in Congress will "try to stop", Senator Chris Murphy says, "but it doesn't seem like Republicans are willing to stand up for democracy abroad or here at home right now".
"Donald Trump is allied with Vladimir Putin, there is no mystery there", he says.
The Ukrainian leader says he will travel to Saudi Arabia where talks on bringing a "lasting" peace will take place.
