Ahead of RLSP's state executive meeting in Patna, party spokesman Madhav Anand said: "The RLSP will not tolerate insult anymore by the BJP."
"Kushwaha tried to meet Amit Shah twice to discuss some issues but he was not given time for it," the spokesman said.
Upon his return from the national capital, Kushwaha told the media that Bihar Chief Minister Nitish Kumar's Janata Dal-United (JD-U) has been trying to split the RLSP and to destroy him.
"Attempt is being made to split the RLSP as Nitish Kumar is hell-bent to destroy me," the Minister said.
There were speculation that Kushwaha was scheduled to make an announcement regarding his continuation in the NDA.
"There will be a big explosion by Kushwaha, it will come as a big setback for the BJP," RLSP leader Nagmani said.
