Ukraine has accused Russia of having taken away around 20,000 children since the invasion began.
Melania Trump says that she sent a letter to Putin about the kidnapped children after the summit in Alaska in August, which Putin then responded to.
A lot has happened since President Putin received my letter in August, says Melania Trump at a press conference.
She says that she has since had a "direct line" to Putin about the children.
We have agreed to cooperate for the best of all parties involved, she says.
As a result of the contact, she claims that eight children have been reunited with their families.
Corrected: In an earlier version of the text, the wrong time for the summit in Alaska was stated.
