BJP leaders including Haryana Chief Minister Manohor Lal and senior leader Anil Jain on Friday intensified consultation with newly elected Independent MLAs for formation of the new government in the northern state.
Mr Khattar, who arrived in the capital, separately met six Independent MLAs and sought their support.
In the 90-member assembly, BJP emerged as single largest party but could win only 40 seats and would thus depend on the Independents to touch the magical mark of 45 plus.
Mr Anil Jain and Mr Khattar also rushed to BJP working president J P Nadda's residence.
Prime Minister Narendra Modi and BJP chief Amit Shah have clearly hinted that incumbent CM Mr Khattar would be again heading a BJP-led regime.
Mr Khattar is set to be elected as new legislature party leader and then he would stake claim with the Governor Satyadev Narayan Arya, source said.
