Blinken warns Ukraine's gains could be reversed without more US aid

US Secretary of State Antony Blinken warned Monday that Ukraine's gains over two years of fighting were all in doubt without new US funding, as NATO's chief visited to lobby Congress. 

"Without it, simply put, everything that Ukrainians achieved and that we've helped them achieve will be in jeopardy," Blinken told a joint news conference with Stoltenberg.

"Absent that supplemental, we're going to be sending a strong and wrong message to all of our adversaries that we are not serious about the defence of freedom, the defense of democracy," he said. 

"It will simply reinforce for Vladimir Putin that he can somehow outlast Ukraine and outlast us," he said.
