An Oklahoma man accused of attaching a homemade bomb to a natural gas pipeline has pleaded not guilty.

Forty-year-old Daniel Herriman entered the plea Tuesday before Magistrate Judge Kimberly West in U.S. District Court in Muskogee.

The FBI says Herriman was arrested Friday after calling 911 and telling the Seminole County Sheriff's Office he had planted a bomb on the pipeline and wanted to surrender.

The FBI alleges Herriman admitted making the device and placing it on the pipeline Aug. 7 with a timer set to detonate at 2 a.m. The device did not explode and there was no damage. FBI spokesman Clay Simmonds said the agency doesn't know of a motive.

The bomb was discovered Wednesday at the Enerfin Resources substation near Okemah in Okfuskee County.

New York Gov. Andrew Cuomo signed a new law Monday to strengthen ethics enforcement for state officials and workers.

The measure, which the Democratic governor proposed and lawmakers approved, establishes a new 14-member Joint Commission on Public Ethics to oversee and investigate compliance by lawmakers. It will also monitor statewide elected officials as well as executive branch and legislative employees while overseeing registration and conduct of lobbyists.

Six members will be chosen by the governor, with at least three from a different political party. Eight will be selected by legislative leaders: four Democrats and four Republicans.

Those functions have been handled by the Commission on Public Integrity, which will close, and the Legislative Ethics Commission, which will have authority to impose penalties following the new panel's investigations. Until the new group is up and running, expected in four months, the current integrity commission with a staff of 46 and with 61 pending cases is stopping investigations and hearings but will continue to collect information.

A federal appeals court agrees with the method a trustee used to calculate how much each investor lost in the multibillion-dollar fraud carried out by Bernard Madoff.

The 2nd U.S. Circuit Court of Appeals said in a written decision Tuesday that investors are only entitled to recover the amount they originally invested with Madoff.

Lawyers for investors had argued that they should be entitled to recover profits as well.

Madoff had told thousands of investors just before his December 2008 arrest that their investments had more than tripled. Madoff claimed the original investment of about $20 billion had grown to more than $60 billion. Prosecutors say it was actually a Ponzi scheme.

Madoff is serving a 150-year sentence after admitting the massive multi-decade fraud.
