(CNN) - President Donald Trump's acting Homeland Security secretary expressed regret Sunday about the timing of immigration raids in Mississippi this week given the emotional state of the nation in the wake of two mass shootings.
McAleenan explained in the interview the immigration enforcement actions -- which occurred in the days after a gunman in El Paso, Texas, targeted Latinos and immigrants, and another shooter opened fire in Dayton, Ohio -- were long-planned.
"In terms of the ICE operations, these are enforcement operations that are part of their daily cycle," he said.
The raids, he said, are "believed to be the largest single-state immigration enforcement operation in our nation's history."
McAleenan wouldn't say on Sunday whether Trump himself was aware of the raids before they began, instead saying, "the President doesn't run law enforcement operations."
