Top national security officials in the Trump administration will testify before Congress this week as lawmakers scrutinize the war in Iran and rising terrorism concerns at home. The hearings come amid controversy over a missile strike that hit an elementary school in Iran, killing more than 165 people, reportedly based on outdated intelligence from the Defense Intelligence Agency. The White House says the strike remains under investigation.

Lawmakers are also expected to question officials about internal disagreements over the conflict, highlighted by the resignation of the director of the National Counterterrorism Center, who said he could not support the war and did not believe Iran posed an imminent threat. The Director of National Intelligence and the Central Intelligence Agency director may face questions about assessments suggesting United States strikes are unlikely to lead to regime change and casting doubt on claims that Iran was preparing to attack first.

The hearings will further examine the leadership of the Federal Bureau of Investigation, whose director has dismissed dozens of agents during his first year. Recent violent incidents in Texas, New York, Virginia, and Michigan have intensified concerns about domestic terrorism, as authorities say they are working continuously to prevent further attacks.
