(NBC News) Two days after the deadliest attack on a military installation in years, questions are mounting about security lapses at the Washington Navy Yard and why the shooter was granted clearance.

Shaken employees are still trying to grasp the tragedy that unfolded Monday.

Meanwhile, the gunman's mother spoke out for the first time.

Cathleen Alexis, not appearing on camera, said "I don't know why he did what he did, and I'll never be able to ask him why.
