"We are observing... The (A K Antony) Committee will decide whether we will align with it... It will decide," party spokesman Meem Afzal told reporters on a volley of questions on the issue of support to the JD-U government.
The Congress had formed a committee headed by Antony to go into the issue of alliances as part of finding new allies ahead of the Lok Sabha polls.
He sidestepped questions on the issue of support to JD-U indicating that the Congress was weighing pros and cons of the matter.
A senior party leader, who declined to be identified, remarked as to how could the Congress take the decision of supporting a party in 17 hours after that party was with the BJP for 17 years.
The JD-U's strategists also expect tacit support from all secular parties, including Congress and CPI.
"We hope the four Congress MLAs and one CPI MLA will either vote in favour of the motion or abstain from voting since they would not like to be seen (to be) with communal forces," said a party leader.
