The Department of Homeland Security was dragging its feet on processing Boston bombing suspect Tamerlan Tsarnaev's U.S. citizenship after a routine background check revealed he had been questioned by the FBI in 2011. Tamerlan, 26, filed an application for citizenship six months ago but immigration officials had not yet made a decision on his case at the time of the Boston Marathon bombings. Authorities knew the alleged bomber had a domestic violence charge on his record but the fact he had been grilled by federal agents is reportedly what threw up red flags, halting the progress of his application. It's not clear what the 26-year-old, who was killed early Friday, was told about why his application was facing delays.
