From GovExec:
The House Homeland Security Committee plans to hold the first congressional hearing next week examining the Boston Marathon terrorist attack and what it says about the state of the nation’s post-Sept. 11 security infrastructure. Committee Chairman Michael McCaul, R-Texas, has launched an investigation into the April 15 bombings and is seeking detailed information about potential security breakdowns from Director of National Intelligence James Clapper, FBI Director Robert Mueller, and Homeland Security Secretary Janet Napolitano. Clapper has also launched his own investigation.
