Obama to Sell Health Care Law to American People VOA News 25 March 2010 Barack Obama Photo: AP US President Barack Obama (File) U.S. President Barack Obama is promoting historic health care reform on Thursday, two days after he signed the sweeping legislation into law. Mr. Obama will be in Iowa City, where he first outlined his health care reform plan as a presidential candidate in 2007. Republicans are solidly opposed to the law. Senate Republicans have successfully challenged a companion measure that makes changes to the new law, forcing the House of Representatives to hold another vote on the smaller bill. Congressional Democrats have also been targeted by threats and acts of vandalism following the health care vote. House Majority Leader Steny Hoyer says at least 10 members of Congress have received threats to themselves or their family members over the past three days. An aide to Senate Democratic Majority Leader Harry Reid says Republicans challenged two provisions in the companion bill that deal with reforms to the U.S. student loan industry.  Reid's spokesman Jim Manley said the Senate parliamentarian ruled that the two provisions violate Senate rules that require all parts of the bill to have a budgetary impact. The Senate is expected to remove the items from the bill later Thursday and send it back to the Democrat-controlled House, which narrowly approved the measure Sunday by a vote of 220 to 211. Manley says he is confident the House will pass it again. Senate Democrats submitted the legislation under those rules to enable it to pass with a simple majority in the 100-seat Senate, where they control 59 seats. The Obama administration backed the separate bill of health care changes in order to persuade more Democrats to support the main legislation, which had already passed in the Senate, and which Mr. Obama signed into law Tuesday. Despite their setback, Senate Democrats used their simple majority to fight off almost 30 Republican amendments to the bill of health care fixes in a marathon session lasting from Wednesday into Thursday morning.
