A Home, Kansas couple has earned national honors for the "home" they've given to six children.

Nick and Jennifer Keller, who have one biological daughter, adopted six children over three years, each of whom was exposed to methamphetamine while in the womb.

Congressman Jerry Moran nominated them as "Angels in Adoption." The honors are given by the Congressional Coalition on Adoption Institute.

“Nick and Jennifer are the parents of a remarkable family with an amazing story,” Moran said in a statement. “Their humble work to help drug endangered children – both by influencing public policy and by giving children a home – is inspiring. The Keller’s are making a real difference in the lives of children and truly are angels for those in need.”

Moran says the presence of illegal drugs, specifically meth, is a very serious problem in many rural Kansas communities. Each year, more than 4,300 Kansas children are exposed to illegal drugs while in the womb. Based on their experiences as adoptive parents, the Keller’s are advocating for legislation in Kansas to better protect children by allowing authorities to intervene when a pregnant woman is using substances and putting her child at risk.

“The fight against meth requires the cooperation of all members of a community,” Moran said. “The Keller’s are an example of caring Kansans doing what they can to break the cycle of meth in our state.”

The Kellers travelled to Washington, D.C. last week to accept the honor.
