Rep. Jim Himes (D., Conn.) said on Wednesday that he thought that all of Syrian dictator Bashar al-Assad's chemical weapons were removed from the country.
Himes was speaking with CNN's Wolf Blitzer, who asked him for his response to President Donald Trump's comments on the Syrian regime's use of chemical weapons on civilians in rebel-held territory on Tuesday.
"Just 24 hours later we get this horrific act against his [Assad's] own people, by the way using weapons that we thought had been negotiated out of the country with the help of Russia," Himes said.
Himes is referring to a deal struck during the Obama administration, when Syria was supposed to turn over its chemical weapons to be destroyed. The deal was struck between the United States and Russia in 2013 after Assad had already used his chemical weapons on civilians.
However, the deal could only reach as far as the weapons that Assad had declared existed. Skeptics of the deal believed that Assad would never turn over a full list of the weapons his regime possessed.
The deal came shortly after then-President Barack Obama had declared his "red line" for the regime's actions.
