Washington, D.C. ? Democratic Sen. Max Baucus of Montana asked his colleagues Saturday to override President Bush’s veto of legislation that would expand a popular children’s health insurance program.

“Every Republican must decide whether they will stand with the president and his veto, or stand with our children and their right to a healthy future,” Baucus said in his party’s weekly radio address.

House Democrats have scheduled for this week a vote to override the president’s veto of legislation that would increase spending for the State Children’s Health Insurance Program by $35 billion over five years. Bush has called for a $5 billion increase.

The effort is not expected to succeed. An override requires a two-thirds majority in the House and Senate, and the earlier House vote fell about two dozen votes short. The Senate approved the increase by a veto-proof margin.
