(CNN) - After a day of conflicting information about his whereabouts, former U.S. Rep. Jesse Jackson Jr. has indeed reported to federal prison to serve a 30-month sentence, a Federal Bureau of Prisons spokesman said Tuesday.

Jackson - once a rising Democratic star whose political career imploded over the use of campaign finances to support lavish personal spending - entered a federal prison camp in Butner, North Carolina, on Tuesday morning, bureau spokesman Ed Ross said.
