Talking to reporters at Mr Singh's residence, Mr Choudhary, a former president of Bihar Pradesh Congress Committee said "I have been close to Dada (Singh) for long and I have come here because of our personal relationship. A political colour ought not to be given to everything".
However, in reply to a query on future political scenario, Mr Choudhary who was accompanied by two other Congress MLAs Dilip Choudhary and Munna Tiwari - cryptically remarked "there are no full stops in politics".
Mr Choudhary was a minister in the Grand Alliance government which consisted of the JD(U), the RJD and the Congress and is known to be close to chief minister Nitish Kumar.
The Congress faction close to Lalu Prasad's RJD has been accusing Mr Choudhary of trying to split the party with the help of his supporters, which led to his removal as the state unit chief a few months ago.
Yesterday at a meeting convened by Congress Legislature Party leader Sadanand Singh, Mr Choudhary was conspicuous by his absence though his close aides maintained that it was because he was out of station and returned to Patna only late in the night.
The chief minister attended the Sankranti feast hosted by his party's state president before heading for the Lok Janshakti Party Office where he was received by Union Minister Ram Vilas Paswan and LJP Parliamentary Board chief Chirag Paswan.
The feast hosted by Mr Paswan was also attended by senior BJP leader and Deputy Chief Minister Sushil Kumar Modi and former Chief Minister Jitan Ram Manjhi, who heads the Hindustani Awam Morcha.
The chief minister also attended another feast organized by BJP MLC Rajnish.
