For a man at the center of so many critical government actions, with a portfolio that includes preventing terrorist strikes and cyberattacks, FBI Director Robert Mueller has mostly avoided the limelight since he joined the bureau just a week before Sept. 11, 2001.

A federal grand jury has indicted two men on charges of obstruction of justice related to the Boston Marathon bombing investigation.
The U.S. Attorney's office for Massachusetts made the announcement on Thursday against two students from Kazakhstan, Dias Kadyrbayev and Azamat Tazhayakov, both 19 at the time of the bombing. If convicted, they face up to 20 years in prison.
