Union Minister launched a sharp attack on Bihar Chief Minister Nitish Kumar a day after his meeting with Congress President Mallikarjun Kharge and Rahul Gandhi in Delhi and said his political downfall is yet to happen. “Everyone wants to become the PM. Nitish Kumar is strong in that. That's why he is pleasing Malikarjun Kharge and got an appointment with Rahul Gandhi. Nitish Kumar should know that the post of 2024 is not vacant,” he added.
