Lawmakers said Wednesday that the FBI is blocking their inquiries into why it closed its files on one of the Boston Marathon bombing suspects after Russia had warned the bureau in 2011 that he might be radicalizing and preparing to join Islamic extremist groups.

"Part of our oversight has to be that case-closed procedure," said Rep. William R. Keating, Massachusetts Democrat. "Something's wrong."
