The Salt Lake Tribune has a fluff piece out implying they are reporting on Obama's past.  The article is about a genealogist and his use of online sources and microfilm to trace Obama's past to his eighth great-grandfather and reporting on what they did.

Odd how the genealogist didn't report on Obama's immediate lineage -- on his mother's side -- that may be traced to espionage.

The Dunham family moved to the Columbia City neighborhood of Seattle, Washington where Stanely landed a job managing a furniture store that was down the street from the regional headquarters of the Communist Party USA. Sources indicate that Ann Dunham’s father, Stanley Armour Dunham, was suspected of espionage during World War II and that Boeing has a 1944 security file on Dunham in connection with sabotage of B-17 aircraft at its Wichita plant and the theft of B-29 blueprints.
