US museum hesitates over Lincoln DNA test

The head of a Philadelphia museum says its sample of Abraham Lincoln's blood may get DNA testing, but some questions must be answered first.

The United States 16th President's blood is on a strip of a pillowcase in the collection of the Grand Army of the Republic Museum and Library.

Cardiologist John Sotos believes Lincoln had a rare genetic disorder and wants the DNA test to prove his hypothesis.

Board President Eric Schmincke says more questions need to be answered about how the artifact will be treated.
