Washington (CNN) Mark Morgan, the acting commissioner of US Customs and Border Protection, on Sunday downplayed an emotional video showing an 11-year-old girl sobbing and begging for Immigration and Customs Enforcement to let her parents go following raids on Mississippi food processing plants.

"I understand that the girl is upset and I get that. But her father committed a crime," Morgan told CNN's Jake Tapper on "State on the Union." Morgan said the girl was reunited with her mother shortly after the video was shot.

The acting CBP chief's comments come after US immigration authorities detained some 680 undocumented immigrants this week in what a federal prosecutor described as a record-setting operation.

US Attorney for the Southern District of Mississippi Mike Hurst told reporters the arrests took place at seven sites in six different cities in Mississippi on Wednesday. The raids, he said, are "believed to be the largest single-state immigration enforcement operation in our nation's history."
