Obama to attend memorial service for victims of Navy Yard shooting

Carney said Obama "will want to mourn the loss of these innocent victims" and "share in the nation's pain" of the shootings. On Monday, 12 people died when a lone gunman opened fire. 

It is unclear when the memorial will be held. But Carney said more details about the memorial would become available soon.

On Monday, Obama said the nation was "confronting yet another mass shooting," calling the victims "patriots" who faced the "unimaginable violence they wouldn't have expected at home."

In brief remarks at the top of a speech on the five-year anniversary of the financial crisis, Obama said the victims on the military installation were "men and women going to work, doing their jobs, protecting all of us."

"They know the dangers of serving abroad, but today, they faced the unimaginable violence they wouldn't have expected at home," Obama said.
