Rick Santorum to receive Secret Service protection

DAVISON, Mich. -- Republican presidential candidate Rick Santorum will receive protection from the U.S. Secret Service this week, Yahoo News has confirmed.

A source close to the campaign said the Secret Service has assigned a team to the former Pennsylvania senator. They will join him Tuesday in Michigan.

Businessman Herman Cain was the first candidate to receive protection last fall, and former Massachusetts Gov. Mitt Romney has had a detail since the beginning of the month.
