First Lady Melania Trump wrote a personal letter to Vladimir Putin in which she criticized the forced kidnapping children, officials said.

Although Slovenian-born Melania Trump was not on the trip to Alaska, she made sure her thoughts were heard and had the note hand-delivered through her husband, two officials told Reuters.

The officials would not divulge the contents of the letter other than to say it mentioned the abductions of children resulting from the war in Ukraine. The existence of the letter was not previously reported.

Russia's seizure of Ukrainian children has been a deeply sensitive subject for Ukraine.

Kyiv has called the abductions of tens of thousands of its children taken to Russia or Russian-occupied territory without the consent of family or guardians a war crime that meets the UN treaty definition of genocide.
