New Mexico fire managers scrambled on Tuesday to reinforce crews battling a third day against an out-of-control blaze at the edge of one of the nation's top nuclear weapons production centers.

The fire's leading edge burned to within a few miles of a dump site where some 20,000 barrels of plutonium-contaminated waste is stored at the Los Alamos National Laboratory, fire officials said.

Doug Tucker, Los Alamos Police Chief, joins Christine Romans this morning to talk about the status of the blaze and the threat that it poses to the nuclear facility.

Firefighters in Texas continue to fight back walls of flames, trying to save homes and livelihoods. Weeks of dry temperatures are fueling hundreds of fires across the state.
