Russian media printed that Christina Freeland's grandfather was Michael Chomiak.  That same Michael Chomiak (not his namesake) was an editor of a Nazi newspaper in Krakow during the war. The newspaper printed many anti-Jewish articles.

The first point can verified in wikipedia. The last two in Holocaust museum in LA which has copies of the newspaper issues: http://www.lamoth.info/?p=collections/controlcard&id=22

Where is disinformation?  Freeland doesn't repudiate allegations, but avoids answering the question.
