New Delhi, Mar 14 (ANI): The Congress on Friday defended its tainted ministers who have been nominated to fight the upcoming general elections. Ignoring opposition from a section against fielding tainted candidates, the Congress on Thursday re-nominated former union ministers Pawan Kumar Bansal and Subodh Kant Sahai in the second list of 71 Lok Sabha candidates. Senior Congress leader Kapil Sibal, instead attacked the BJP, saying that maximum number of its candidates have a criminal background.
