Secretary of State Rex Tillerson said on Tuesday that Russia is ultimately to blame for Monday's suspected chemical attack by the Assad regime in Syria, Politico reports.

Why it matters: This follows President Trump's rebuke of Russia in a Reuters interview last week, for "not helping us at all with North Korea." That's a change of tune — Trump repeatedly said during the campaign that he thought having a positive relationship with Russia would be beneficial.

• Tillerson was speaking on Tuesday in France at the launch of the International Partnership Against Impunity for the Use of Chemical Weapons.
• He said: "Russia's failure to resolve the chemical weapons issue in Syria calls into question its relevance to the resolution of the overall crisis."
