With the Bush administration pushing hard for a quick Congressional nod for the landmark Indo-US civil nuclear deal, a small group of senior Democratic lawmakers have demanded the detailed examination of the pact. The three-person group led by Massachussetts Congressman Edward Markey has said that there are many lingering questions about the deal that require further examination and hence Congress should rule out any rush for an expedited vote for its ratification. The group's demand has come in the wake of the reports that the 30-day rule for the legislation to be considered will be waived to meet the September 26 deadline when the present session on the Congress is ending. Markey, a senior member of the House Energy and Commerce Committee, has been joined in the call by California Democrat Ellen O Tauscher, the Chair of the House Armed Services Strategic Forces Subcommittee and John Spratt, the chair of the House Budget Committee.
