Seven Americans are dead, the Pentagon is dodging questions, and Defense Secretary Pete Hegseth is promising more casualties. Congress must open a formal investigation now. Hegseth has provided no accounting of the chain of command decisions behind Operation Epic Fury. When footage emerged appearing to show a U.S. Tomahawk missile near a girls' school his administration had blamed on Iran, he offered only: "It's being investigated." That cannot be the last word. Congress has the authority — and the obligation — to find out what decisions were made, by whom, and why American troops keep dying with no transparency from the Pentagon. We call on Congress to open a formal investigation into Pete Hegseth and the Department of Defense: subpoena Hegseth to testify before the Armed Services Committees, demand a full accounting of every decision made in Operation Epic Fury, and determine who is responsible for the deaths of seven U.S. service members. American troops deserve better than a Defense Secretary who treats their deaths as a PR problem. Congress must act.
