White House spokesman John Kirby told reporters that Washington does not see evidence to suggest Russia is readying to use nuclear weapons in Ukraine. Kirby said the same statement last month as well, although The New York Times used “multiple senior American officials” in an article saying Russian generals were in talks of “when and how Moscow might use a tactical nuclear weapon in Ukraine.”
From RT:
The threat of a nuclear war has been a hot topic recently after Putin vowed to defend Russia’s territory and people using “all the forces and resources we have” in late September. His remarks were then widely interpreted by Western pundits and officials as a veiled nuclear warning, which prompted US President Joe Biden to caution about a potential “nuclear Armageddon.” Putin clarified his statement later by saying that Moscow has not even mentioned tactical nuclear weapons, let alone threatened to use atomic weapons. His words, however, did not alleviate fears in Washington, as Biden continued to wonder why Russia keeps “talking about” nuclear weapons if it does not plan to use them.
