The issue is part of an ongoing disagreement Texas and the EPA have over how pollution is regulated in the state, said Terry Clawson, a spokesman for the Texas Commission on Environmental Quality. In recent weeks, debate has focused on the state's use of so-called flexible permits, which sets a general limit on how much pollutants an entire facility can release.

In a news release, Abbott's office criticized the EPA for taking more than a decade before deciding to reject the law and said it filed the legal challenge "in an effort to defend the state's legal rights and challenge improper overreach by the federal government."

It's a simple matter of math: Elena Kagan's nomination to the Supreme Court has complicated the government's effort to force the tobacco industry to cough up nearly $300 billion.

If confirmed by the Senate as a justice, Kagan would have to sit out high court review of the government's decade-old racketeering lawsuit against cigarette makers. That's because she already has taken sides as solicitor general, signing the Obama administration's Supreme Court brief in the case — an automatic disqualifier.

Kagan is expected to step aside from 11 of the 24 cases the court has so far agreed to hear beginning in October.

Without her, the government and anti-tobacco advocates could find it difficult, if not impossible, to find a fifth vote to allow the government to seek $280 billion of past tobacco profits and $14 billion for a national campaign to curb smoking.

Vincent Smothers pleaded guilty to eight counts of second-degree murder and a gun charge in exchange for a minimum sentence of 52 years in prison. With credit for time served since his arrest, he could be freed when he's about 80 years old.

Smothers, 29, shocked police two years ago when he confessed to the eight Detroit slayings during around-the-clock interrogations. He told investigators his hits were all related to the drug trade except for the final one, the killing of Rose Cobb on the day after Christmas in 2007.

"He's just glad there's closure for everybody," defense attorney Gabi Silver told The Associated Press after the hearing in Wayne County Circuit Court, where jury selection was scheduled to begin Monday for the Cobb slaying.

Superior Court Judge Marsha Revel issued a warrant for Lohan's arrest after the 23-year-old actress skipped a mandatory court appearance last week.

Revel also ordered that the star abstain from alcohol, wear an alcohol-monitoring bracelet and submit to random weekly drug testing.

Lohan avoided arrest by posting $100,000 bail, but still faces the other conditions imposed by the judge.

The actress was due in court last week for a progress report on her probation stemming from two arrests in 2007. Revel said there is probable cause to believe that Lohan violated the terms of her probation. A formal hearing will be held to determine if she is in compliance with the court's conditions.
