Sushil said Nitish has insulted Prime Minister Narendra Modi and the people of Bihar.
As per the trends, the NDA was leading in the elections.
After reaching Patna on Thursday night, Shakti Singh Gohil, Congress's Bihar in-charge, asserted that the situation won't have risen had RJD president Lalu Prasad Yadav been out of jail. Lalu is serving a sentence in a fodder scam case in present-day Jharkhand.
Bihar chief minister Nitish Kumar on Thursday rejected claims by Bharatiya Janata Party MP and his former deputy chief minister Sushil Modi that the Janata Dal-United had split with the National Democratic Alliance as the chief minister was not made the Vice President.
Paswan, who has chosen to plough a lonely furrow in the ongoing assembly elections, reiterated that the LJP was and will remain loyal towards the BJP, which was staring at the spectre of yet another "paltimaar" (volte face) by the JD-U president.
A crowd of Tejashwi supporters that had gathered outside the 10 Circular Road residence of former chief minister Rabri Devi expecting a victory is thinning now.
A former protege of the JD-U de facto leader, Kushwaha, had revolted against Kumar in 2013, giving up his Rajya Sabha berth and floated his own outfit.
The party, however, did not announce as whether it would merge with any other party or become part of some other alliance.
Releasing the manifesto titled 'Badlav Ka Sankalp' (commitment to change) in the presence of All India Congress Committee (AICC) general secretary Randeep Singh Surjewala and other Mahagathbandhan leaders, Tejashwi Yadav said their government, if elected, would first approve the process for appointments on about 10 lakh jobs in the government.
