An American human rights envoy said Thursday that China provided no useful information when probed about specific cases of individuals who have been detained or who disappeared in a major crackdown on dissent in recent months.

Hundreds of lawyers, activists, and other intellectuals have been questioned, detained, confined to their homes or have simply disappeared, apparently to squelch any chances of the kind of popular uprisings roiling the Middle East and North Africa. The clampdown on dissent is the broadest and harshest in years by China's Communist government.

Michael Posner, U.S. assistant secretary of state for democracy, human rights and labor, said that his delegation received no satisfactory answers to its questions about Teng Biao, a law professor who disappeared in February, and the artist Ai Weiwei, who was apparently detained by authorities April 3 but has yet to be formally charged.

"We need to and will continue to raise these issues in a range of forums," Posner said. "The most senior government officials in the United States are deeply concerned about the deterioration of human rights in China over the last several months."

Federal authorities have charged two men with running an insider trading scheme that netted more than $30 million with information stolen from law firms.
Garrett Bauer is scheduled to appear in U.S. District Court in Newark, N.J., on Wednesday afternoon. Matthew Kluger will make his first appearance in federal court in Alexandria, Va.

They're accused of trading on inside information stolen from Wilson Sonsini Goodrich & Rosati, a law firm with offices in Washington, D.C., New York, San Francisco and Hong Kong.

Authorities also allege the decades-long scheme used information stolen from prominent New York law firms Cravath Swaine & Moore and Skadden, Arps, Slate, Meagher & Flom.

The Supreme Court has rejected an appeal challenging campaign disclosure laws in Washington state.

The court on Tuesday let stand without comment a federal appeals court ruling that upheld the state's disclosure requirements. Human Life of Washington challenged the requirements as a violation of the First Amendment. The group didn't want to reveal its donors in a 2008 campaign opposing an assisted suicide ballot measure.

The San Francisco-based 9th U.S. Circuit Court of Appeals said the disclosure requirements "have become an important part of our First Amendment tradition."

Rosemary Vandenbroucke, 28, of Hong Kong agreed to pay $385 in fines and $985 for damage to the "Biggest Little City in the World" arch and a fire hydrant, said Dan Wong, criminal division chief for the city attorney's office.

Tammy Riggs, a lawyer for Vandenbroucke, didn't immediately return a phone call from The Associated Press seeking comment on the plea deal.

Reno Municipal Court Judge Jay Dilworth accepted the plea with no other penalties, Wong said.

Nobody was injured in the crash, but authorities said the 40-foot motorhome was substantially damaged.

Vandenbroucke was originally charged with three misdemeanors—vehicular hit-and-run, failure to maintain insurance and making an improper right turn.

The Labor Day crash occurred a day after the model was arrested at the Burning Man counterculture festival north of Reno and charged with possession of a controlled substance.
