Biden says Russian invasion of Ukraine "remains distinctly possible," but there's still room for diplomacy

President Biden said Tuesday that a Russian invasion of Ukraine "remains distinctly possible," but held out hope that a diplomatic resolution could be reached.

"This is about more than just Russia and Ukraine — it's about standing for what we believe in," Mr. Biden said. 

Mr. Biden said the U.S. has "not verified" Russian claims that it has started a troop drawdown near Ukraine, and U.S. analysts still believe there are 150,000 troops circling the border with Ukraine and Belarus.
