President Trump told Prime Minister Theresa May in a call this afternoon that the U.S. would be with the U.K. "all the way" over the poisoning of ex-spy Sergei Skripal with a Russian-manufactured nerve agent on U.K. soil, according to Downing Street's readout of the call.

The White House said that Trump agreed that Russia "must provide unambiguous answers" and said that Trump and May are united in calling for "the need for consequences for those who use these heinous weapons."

The backdrop: Trump hedged this morning, saying he wanted to wait to get the "facts straight" before condemning "Russia — or whoever it may be."
