WASHINGTON (AP) - The Homeland Security Department is wasting time and money on its current plan for developing technology to detect nuclear material at the nation's borders, two senators say.

Sens. Joseph Lieberman, I-Conn., and Susan Collins, R-Maine, are slamming the department for not having a strategic plan to develop critical technology that could prevent a nuclear terrorist attack on the U.S.

It's not the first time the department has been criticized for the nuclear screening efforts. The Obama administration blames most of the problems on the Bush administration, but Lieberman and Collins say the current administration isn't working fast enough to fix it.
