Couple devastated by Russian adoption ban

Robert and Kim Summers have a crib by their bed, a stroller waiting in their dining room, and clothes for a baby boy who may not be permitted to come home to them.

The couple has visited Preston in Russia and they felt a connection. Kim Summers says seeing him was "the most joyful day" in her life since her wedding day.

They were eager to welcome a baby into their family after trying unsuccessfully to have their own child.  But Friday, Russian President Vladimir Putin signed a law that prohibits the adoption of Russian children by people in the U.S.

The measure goes into effect Jan. 1 and is viewed as retaliation for a U.S. law that imposes travel and financial restrictions on human rights abusers in Russia

Like others trying to adopt, the Summers have spent years and thousands of dollars on a process that can be emotionally exhaustive. They are committed to Preston and already view themselves as his parents. Robert told CNN's Randi Kaye, "If I have to spend the rest of my life to bring him home, I will do so."
