There may be a reason other than security that the campaign doesn't want Signator talking to the press.

During Obama's 2004 Senate race, in the weeks after Obama's convention speech had marked him as a rising star, Signator accompanied Obama to an African-American parade in Chicago. According to an Obama biography by Chicago Tribune veteran David Mendell, the crowd chanted "O-ba-ma! O-ba-ma! O-ba-ma!" and gave the young candidate such a passionate reception that Signator, identified by Mendell as Obama's "driver and bodyguard," joked that he "thought Barack was going to rise up over the people and start saying, 'My children, my children, I have come to free you"

It gets scarier and scarier....

"A retired military officer in Pacific Grove alerted me to the Obama-Odinga connection, and Obama's active campaigning and support of Odinga in 2006.

Others were able to confirm that Obama did support Odinga, and that that Odinga incited racial violence that led to the deaths of over 1,500 and the displacement of 500,000 more.

Obama did "campaign" for Odinga by any reasonable take, and Obama's trip to Kenya was paid for by the US taxpayers. Past that, your own mileage.

Specifically, during his 2006 Kenyan tour Obama gave a speech in Kenya ripping on the existing government and then toured with Odinga, during which tour he "starred" at several Odinga rallies. It's pretty tough to find a way to rationalize that away from stumping FOR Odinga, given Obama's "star" status in Kenya during the trip. Before Obama went to Kenya on that trip, Odinga visited him in Washington several times over two years, and he sent his foreign policy aide as an advance man."
