President Donald Trump is downplaying the possibility of sending Ukraine long-range weapons as Kyiv awaits an injection of U.S. weaponry that it hopes will help it beat back an intensifying Russian air offensive.

Russia continued its nightly bombardment of Ukrainian cities overnight into Tuesday, after President Donald Trump said the U.S. would send military equipment to Kyiv.

Trump’s threats of secondary tariffs are “never going to go anywhere” as long as he is unwilling to impose costs on Moscow directly, Keir Giles, a senior fellow at the London-based Chatham House think tank, told NBC News Monday.
