"Environmental groups sued the Obama administration Tuesday for scrapping a stricter limit for smog-forming pollution, saying the decision violated the law and put politics ahead of protecting public health."
"The lawsuit filed in the federal appeals court in Washington by four environmental and public health groups came after the White House last month said it would not support setting a new standard for ground-level ozone until 2013, outraging environmentalists.
Environmental Protection Agency chief Lisa Jackson had said in 2009 at the recommendation of scientific advisers that she wanted a more stringent standard to protect public health.
But President Barack Obama, facing a re-election race in 2012 and under pressure from business groups and Republicans, rejected the final proposal. The White House said setting a new standard would create 'needless uncertainty' at a time when the economy was struggling."
