“This consultation has not yet taken place, but it is an essential part of the process,” Buck continued. “And meaningful consultation should happen before any military action is taken.”

Buck also demanded that the president “explain his decision publicly, clearly and resolutely” if he decides to act.

“More than just to Congress, the president has an obligation to the American people to explain the rationale for the course of action he chooses; why it’s critical to our national security; and what the broader strategy is to achieve stability,” Buck wrote.
