Rana was elected to the Lok Sabha on a Rashtriya Janata Dal (RJD) ticket when Jharkhand was a part of Bihar.

When Jharkhand was carved out from Bihar in 2000, 53 of the 61 cases related to the fodder scam were transferred here.

For speedy trial seven CBI courts were constituted. The special CBI courts have delivered judgement in 30 cases. More than 230 accused have been convicted.

The CBI held former railways minister and RJD chief Lalu Prasad and former Bihar chief minister Jagganth Mishra accused in five fodder scam cases.
