US President Donald Trump has put forward a rough timeframe for his meeting with Russian President Vladimir Putin in Budapest.
"I'll be meeting him probably over the next two weeks," Trump told reporters in the Oval Office.
Trump also addressed the Ukrainian request for US-made Tomahawk missiles, seemingly cooling off on providing them after the phone call with Putin.
He warned the United States could not "deplete" its own stock of the missiles, adding that when he addressed the issue with Putin, he "didn't like the idea."

Zelenskyy aims to use Gaza ceasefire momentum for peace in Ukraine
Ukrainian President Volodymyr Zelenskyy said he was planning on building on the momentum currently in place since a ceasefire agreement in Gaza was reached, ahead of his meeting with US President Donald Trump on Friday.
"We expect that the momentum of curbing terror and war that succeeded in the Middle East will help to end Russia’s war against Ukraine," Zelenskyy said on X. "Putin is certainly no braver than Hamas or any other terrorist."
