Back in April we reported that John Sotos, a cardiologist and consultant for the tv series "House", wanted to test a pillowcase that President Abraham Lincoln had lain on while dying. Sotos believes that Lincoln had a rare genetic cancer syndrome called multiple endocrine neoplasia type 2B (MEN2B). He believed that Lincoln's blood remains on the pillowcase, and he could prove or disprove his theory.
On May 5th, the members of the board of the Grand Army of the Republic Museum and Library in Philadelphia's Frankford section decided to not allow testing of the artifact.
You can read all about their decision in the Philadephia Inquirer.
