Lawmakers should consider increasing the amount of time that terror suspects are tracked in federal databases, according to a Republican chairman.

House Homeland Security Committee Chairman Michael McCaul (R-Texas) said lawmakers might need to require U.S. agencies to keep suspects in databases for longer as a result of the Boston Marathon bombings.

“We’re going to have to look at — in term of investigatively — how we keep these leads on file, maybe keep the databases on file a little bit longer, and how we could keep people like that out of the United States,” McCaul said on Friday.
