The House of Representatives has just started the session at which a crucial vote on health care benefits reform is expected.

The democratic leaders expressed confidence they would get the 216 votes needed to pass historic health care reform legislation in the House, while Republicans promised to keep fighting, with one GOP House member saying they would use "every means at our disposal" to stop the bill from becoming law.

The decisive House vote scheduled for later today could define the success or failure of President Obama's administration.
