Here’s a look at some of the stories CNN.com reporters are working on Tuesday:
Health care – President Obama will sign sweeping health care reform legislation into law at the White House at 11:15 a.m. Tuesday, according to two Democratic officials familiar with the planning. Once signed, the Senate will take up House fixes to the law, which Republicans are already trying to stop. Their first attempt to prevent debate was knocked down last night by the Senate parliamentarian, according to Democratic and Republican sources.
The signing comes as ten states plan to file a federal lawsuit challenging the constitutionality of the new health care reform bill, according to Florida's attorney general.
Obama will continue to discuss the reform in hopes of pulling in line many members of the skeptical public. We'll continue to provide live coverage and today we'll take a look at what the health care bill means to you, when things will begin taking effect and whether Obama has used up much of his political capital on this one issue and how it might impact the rest of his agenda.
