The FBI has made an arrest in its nearly 5-year-old investigation into who placed pipe bombs in Washington on the eve of the Jan. 6, 2021, riot at the U.S. Capitol, a law enforcement official told The Associated Press on Thursday.
The arrest marks the first time investigators have settled on a suspect in an act that had long vexed law enforcement, spawned a multitude of conspiracy theories and remained an enduring mystery in the shadow of the dark chapter of American history that is the violent Capitol siege.
