Congressional members move forward with efforts to override the veto for children's health care...

Labor unions and advocacy groups, including MoveOn.org, said yesterday they are joining the effort to override the veto and expect to spend more than $1 million to persuade lawmakers to oppose Bush. The campaign will include television advertising and phone calls to lawmakers to argue for expansion of the program, representatives of the groups said in a conference call with reporters yesterday. The organizations are targeting members of the House, which approved the legislation last month without the two-thirds majority needed to override a veto. The Senate passed the measure with a veto-proof majority.
