The KGB, now called the FSB sent sleeper agents called "illegals" to the US to court powerful American business men. Anna Chapman was the most famous one caught; but there were certainly others. As reporters have proved Melania's story all sorts of curious things come up. She got claimed a degree from a non-existent university. She claimed that she had to travel to eastern Europe every three months to renew her visa, even though that wasn't a requirement for a someone under an HB3. I'm not saying she was using the excuse of renewing her visa as a cover for meetings with her KGB bosses, or that she has all these fake details in her biography because it is just KGB fiction, I'm just noting that many people are asking questions. It's very weird.
