Department of Homeland Security Secretary Kristi Noem's bag was stolen at a Washington restaurant Sunday, according to a DHS official.

Noem had $3,000 in cash in her bag, along with her passport, makeup bag, DHS access card, apartment key and other items.

A man wearing a mask walked by the secretary's table and snatched the bag.

A DHS official said the secretary had the cash because her family was in town and she was treating them to Easter festivities.

"Her entire family was in town including her children and grandchildren -- she was using the cash withdrawal to treat her family to dinner, activities, and Easter gifts."

The Secret Service is investigating, according to the DHS official. The Secret Service deferred any comment on the incident to DHS.
