reported on Friday that 19-year-old Dzhokhar Tsarnaev, the man being hunted by police as a suspect in Monday's bombings, became a U.S. citizen on Sept. 11, 2012 after coming to the country on a tourist visa in April 2002. Before becoming a citizen, he sought asylum in September 2002 and gained lawful resident status in February 2007.

Dzhokhar Tsarnaev's 26-year-old brother, Tamerlan Tsarnaev, was killed in a firefight with police on Thursday night. His legal status was not immediately known.

Earlier this week, Rep. Steve King (R-IA) speculated that the bombings in Boston had been perpetrated by a “foreign national” and that Congress should proceed with caution on any immigration reform efforts. Rep. Louie Gohmert (R-TX) also warned that “radical Islamists” were “being trained to come in and act like Hispanics.”
