By Steve Holland WASHINGTON (Reuters) - President Barack Obama mounted a vigorous effort on Thursday to show his signature healthcare law is working and dismissed Republican critics who are using flaws in Obamacare to campaign for ousting Democrats from the U.S. Congress in November. Appearing in the White House briefing room days before leaving the national stage for a week-long trip to Asia, Obama used a news conference to make the case that the Affordable Care Act had mended nicely from its disastrous October rollout. For the healthcare law to succeed, young, healthy people must sign up and pay premiums to offset the healthcare costs for older Americans. Obama's remarks reflected deep concerns at the White House that Republicans may be able to topple Democrats from control of the U.S. Senate in November elections and build on their majority in the House of Representatives.
President Barack Obama on Thursday called on the Congress to pass comprehensive immigration reform, which he said was being held back by Republican leaders in the House of Representatives. "There is bipartisan support for comprehensive immigration reform," Obama said at a news conference. The Congress should act. "Right now what's holding us back is House Republican leadership not willing to go ahead and let the process move forward." Obama said there were Republicans in both the House and Senate who know immigration reform "is the right thing to do." "I also know it's hard politics for Republicans because there are some in their base that are very opposed to this," he said.
