(CNN) -- Illinois senator and Democratic presidential candidate Barack Obama has been placed under the protection of the Secret Service, the agency said Thursday.
The Secret Service would not divulge the reason for the protection, which came at the request of the Obama campaign.
The organization said in a written statement that Homeland Security Secretary Michael Chertoff, "after consultation with the congressional advisory committee, authorized the United States Secret Service to protect presidential candidate Senator Barack Obama."
Chertoff works with a congressional panel made up of half a dozen members of Congress, including House Speaker Nancy Pelosi and Senate Majority Leader Harry Reid.
"As a matter of procedure, we will not release any details of the deliberations of assessments that led to protection being initiated," the Secret Service statement said.
I understand why the Secret Service won't divulge details, still I wish we new the nature of the threats.Â Were they domestic or foreign?Â A lone nutjob or some KKK-like organization?Â
By the way, in case you missed it, the Secret Service was moved from Treasury to Homeland Security with the creation of the latter in 2002.Â
