White House adviser Stephen Miller is searching for solutions to the United States’ immigration and border security problem.

During an interview on CBS’ “Face The Nation,” Miller was asked about the recent reports that a 7-year-old girl died while in the care of U.S. Customs and Border Patrol.

“Our hearts break for the tragic death of the 7-year-old girl,” Miller began. “The loss of that precious life is horrifying. It is a painful reminder of the ongoing humanitarian tragedy that is illegal immigration and the misery that it spreads.”

While reports dispute exactly what happened to the girl, Miller pointed out how dangerous the journey over the border can be and that Border Patrol often helps migrants in remote areas.

He also brought up judges allegedly defending relaxed immigration policies.

“One of the great tragedies that is going on in our country today is the loopholes in our immigration laws and the deficiencies in our immigration laws,” Miller said, “and left-wing, activist judicial rulings that incentivize the most vulnerable populations to come to our country.”

The adviser has been very critical in the past about Democratic lawmakers and their rhetoric toward immigration. Miller claimed the country was at a turning point and that lawmakers should decide what they will support.

“This is a very fundamental issue,” Miller said. “At stake is the question of whether or not the United States remains a sovereign country. Whether or not we can establish and enforce rules for entrance into our country. The Democrat Party has a simple choice. They can either choose to fight for America’s working class or to promote illegal immigration.”
