Obama Facebook poll

WASHINGTON, Sept. 29 (UPI) -- A poll was posted -- and since removed -- on the Facebook social networking Web site, asking whether the president of the United States should be killed.

Federal authorities are investigating whether the posting was an attempt to incite violence against President Barack Obama or a sophomoric prank. Voting options were "yes," "no," "maybe" and "if he cuts my healthcare."

Facebook said the question was posed through a third-party application. The company is working with federal investigators to track down who is responsible for the possible threat.

The poll was put up Saturday and removed by Facebook officials Monday. The Christian Science Monitor said several hundred people voted on the poll before it was pulled.
