Representatives of pregnancy crisis centers, children's agencies, domestic violence shelters and Catholic charities teamed up Monday to tout the benefits of tax breaks for benevolent organizations.

Republican House leaders have defended tax credits as good economic development tools and have denounced efforts to sharply curtail them.

Rep. Shane Schoeller, R-Willard, who organized Monday's news conference with the charities, said he wants to delay any changes to Missouri's tax credit system for at least a year so it can be studied further.
