WASHINGTON (AP) — Gen. John Campbell, the army’s vice chief of staff and nominee to lead U.S. forces in Afghanistan, cited his son’s experiences as a soldier there to answer a senator’s tough questions last year about a troubled intelligence technology system.

But after an inquiry from The Associated Press, the Army acknowledged this week that Campbell misspoke. He also omitted key facts as he sought to defend a $4 billion system that critics say has not worked as promised. Campbell will likely face more questions about the intelligence network at his confirmation hearing on Thursday. Gathering and making sense of intelligence in Afghanistan will remain a priority even as U.S. troops draw down.
