( CNN) Democratic Rep. Tulsi Gabbard said she’s “skeptical” that Bashar al-Assad’s regime was behind the chemical weapons assault that killed dozens of people in Syria.

Gabbard’s remarks came after Secretary of State Rex Tillerson told, “We have a very high level of confidence that the attacks were carried out by aircraft under the leadership of the Bashar al-Assad regime, ” and President Donald Trump told: “There can be no dispute that Syria used banned chemical weapons.”

CNN’s Wolf Blitzer asked Gabbard if she didn’t belief the President, the secretary of state and Pentagon officials, all of whom came to the same judgment: that Assad’s regime was responsible. Gabbard mentioned the previous invasion of Iraq, and the intelligence that suggested Iraq had weapons of mass destruction, which turned out to be false. “So, yes, I’m skeptical, ” she told.
