Agencies plotting response to Mexican violence

Homeland Security Secretary Janet Napolitano said Thursday afternoon that a plan is being worked at "the highest levels" of the U.S. government to address escalating levels of violence in Mexico.

"The issue is getting top attention in multiple agencies of the U.S.," she told reporters.

She declined to provide details on the plan or specifically when it will be made public.

But part of the plan involves contingency efforts if violence spills over into the United States. Napolitano said the plan was put together without consulting state and local officials, so her office has now sent department officials to border areas to meet with them.

Meanwhile, House Speaker Nancy Pelosi said on Thursday she is asking House Intelligence Committee Chairman Silvestre Reyes, D-Texas, House Armed Services Committee Chairman Ike Skelton, D-Mo., and House Foreign Affairs Committee Chairman Howard Berman, D-Calif., to take a delegation to Mexico to address rising drug violence.
