The Secretary said he had no plans to meet with Consumer Protection officials Friday, but said he visited the home where three of the infants lived before they died.
"This is a critically important issue for us in the Army," McHugh said. "We are co-operating fully with the Consumer Protection Commission and continue to pursue every possible avenue until we hopefully get some answers."
Earlier this week, Fort Bragg officials announced their finding indicated no link between the on post homes and 10 infant deaths.
On Friday, McHugh called the results inconclusive at best.
McHugh said he hasn't heard of any mysterious infant death at other Army post, but has ordered CID investigators to check records for any similar incidents and circumstances. He said pinpointing a cause will be a tough challenge.
"I can assure the families that we ate taking the possibly of this challenge very seriously pursing it with virtually every resource that we have available beyond that we have no reason at this time to suspect that Army housing here at fort Bragg or other places is anything but safe but we are not going to take anything for granted pursue it for those great families," McHugh said.
He also said the investigation at Fort Bragg is far from over.
