UN Ambassador Nikki Haley said at a UN Security Council meeting that the “U.S. believes that Russia is responsible” for the nerve agent attack on an ex-spy in the UK.

"This is a defining moment," she said. "One member stands accused of using a chemical weapon on the sovereign soil of another. The credibility of this council will not survive if we fail to hold Russia to account."

The backdrop: These are strong remarks from Haley, particularly compared to President Trump's comments yesterday, in which he hedged on whether Russia was responsible. Her comments follow British P.M. Theresa May's decision to expel 23 Russian diplomats and call on the security council to take up the matter.
