Assad says he did not have 'anything to do' with alleged chemical attack

“He basically said, ‘There has been no evidence that I used chemical weapons against my own people,’” Rose said. “‘And if, in fact, the administration has evidence, then they should show that evidence and make their case.”

Assad suggested that if the United States did launch a military strike, he and his allies would retaliate in some way, Rose said.

The PBS anchor said that there was “a clear sense” that Assad was closely watching what was happening in Washington, where President Obama has asked Congress to approve military action in Syria.

When Rose asked whether Assad expected an attack, he said the Syrian president responded: “I don’t know. We’re prepared as best we can.”

“He was calm. He knew the situation he was in,” Rose said.
