White House Chief of Staff Denis McDonoughDenis Richard McDonoughEx-Obama chief of staff: Obama's Russia response was 'watered down' Former Obama officials launch advocacy group aimed at Trump's foreign policy Obama: Bannon, Breitbart shifted media narrative in 'powerful direction' MORE said Sunday that no one is disputing the intelligence that Assad was responsible last month’s alleged chemical attack, which the U.S. said killed more than 1,400 people in the Damascus suburbs.

“I’ve been talking to dozens of members of Congress over the last week. Not a single one of them so far has rebutted or refused the intelligence, which is to say, everybody agrees that on August 21, Assad used chemical weapons against his own people.”

Amash said that he was not rebutting the evidence presented in the classified briefings, but was taking issue with the public statements from the administration.

He did not, however, elaborate on what specifically he felt was being embellished. The libertarian-leaning Republican said that the briefings have nevertheless made him “more skeptical about the situation.”

“The briefings haven’t given me comfort,” he said.
