The U.S. House of Representatives on Friday filed a lawsuit against the administration of President Barack Obama over his signature health care reform legislation, fostering another showdown between Republicans and Democrats on Capitol Hill. The filing came as the president was headed to Las Vegas to rally public support for his executive order to overhaul immigration reform. On Thursday evening in an emotional address to the nation, Obama announced the measure that will stop deportations of millions of undocumented immigrants. Republican House Speaker John Boehner on Friday expressed his anger over what he called the president’s repeated abuse of his executive authority. "With this action, the president has chosen to deliberately sabotage any chance of enacting bipartisan reforms that he claims to seek," Boehner said of the immigration order. "And as I told the president yesterday, he is damaging the presidency itself." Contests unilateral action In a separate written statement, Boehner said the House is filing a lawsuit because the president has acted unilaterally several times to delay parts of the Affordable Care Act implementation – without consulting Congress. House Republicans have bitterly opposed the president’s health care reform, and they also oppose the new executive order on immigration. The Democratic-led Senate passed comprehensive immigration reform legislation in June 2013, but the Republican-led House has not taken up the issue. Boehner said Obama has destroyed any remaining trust he might have had with Republican lawmakers. Boehner said the president’s action would put more lives at risk by encouraging illegal immigration to the United States. via Lawmakers Sue Obama Administration.
