New Delhi, Feb 6 (ANI): BJP leader Ravi Shankar Prasad on Thursday said that the Congress has been running a systematic and malicious campaign against former Gujarat Home Minister and Narendra Modi's aide Amit Shah for years in Gujarat and all over the country, which has now been demolished. The CBI has not named Shah, whom it had interrogated earlier, in its second charge-sheet in the Ishrat Jahan encounter case.
