U.S. District Judge James B. Zagel also dismissed defense attorneys' concerns that U.S. Supreme Court decisions expected by the end of June could unfairly complicate the trial.

Zagel said he saw no reason to delay the trial's June 3 start date.

If the date holds, voters will likely hear months of testimony about the former Democratic governor's alleged misdeeds as the party tries to retain his former seat and the U.S. Senate seat once held by President Barack Obama.

Prosecutors say Blagojevich schemed to sell or trade that Senate seat and used his power to illegally pressure political campaign donors.

Blagojevich has pleaded not guilty to racketeering conspiracy and other charges.

A federal judge on Tuesday said farmers can harvest their genetically engineered sugar beets this year, ruling the economic impact too great and that environmental groups waited too long to request that the crop be yanked from the ground and otherwise barred from the market.

Nearly all sugar beets planted are genetically engineered and the crop accounts for half the nation's sugar supply.

U.S. District Court Judge Jeffrey White last year sided with the environmental groups when he ruled that federal regulators five years ago improperly approved the genetically engineered crop for market. White said in September that further environmental studies are required before the United States Department of Agriculture can decide the issue but didn't decide the next legal steps.

In January, the Center for Food Safety, Earthjustice and several other groups and organic farmers asked White to immediately halt the planting and harvest of all genetically engineered beets while determining how to resolve the lawsuit, which was filed in 2007.

The groups sued the USDA over its approval, and the biotech company Monsanto Co., which develops genetically engineered seeds, joined the lawsuit on the government's side.

The groups and organic farmers fear the biotech beets will cross-pollinate with conventional beets, as well as Swiss chard, and upset consumers who shun genetically engineered products.

Blagojevich's attorneys asked U.S. District Judge James B. Zagel last week to postpone the trial, which is scheduled to begin June 3, by five months.

Prosecutors told Zagel that Blagojevich "has repeatedly and publicly challenged the legitimacy of the charges against him."

"As a result, the public has a strong interest in the expeditious resolution of the charges — an interest that would not be served by an unnecessary delay of five months in the start of his trial," prosecutors said.

They also reminded Zagel that by June 3, Blagojevich will have had more than a year to prepare with a number of lawyers working on his behalf.

Blagojevich is charged with racketeering conspiracy and other offenses that include allegations he schemed to sell or trade President Barack Obama's former U.S. Senate seat and illegally pressured people doing business with the state for campaign contributions. He has pleaded not guilty.

His attorneys have asked that the start of the trial be delayed until Nov. 3, saying they must review an overwhelming number of documents and there is no way they can have the job done by June.

Robbins Umeda LLP, a California-based law firm, announced this week that it has launched an investigation into the recent acquisition of Broadview Security by Tyco International.

According to a statement issued by the firm, the investigation will look into possible breaches of "fiduciary duty" and other state laws by the Broadview board of directors.

The firm added that is will also determine if the acceptance and recommendation of the offer by the Broadview board was fair and if they disclosed all information necessary to share holders so that they could make an informed decision on how to vote.

Broadview share holders who want more information can contact attorney Lauren Levi at 800-350-6003.

A federal court has upheld regulations that require cable TV companies to make channels they own available to satellite TV providers and other rivals on equal terms.

Friday's ruling by the U.S. Court of Appeals for the District of Columbia leaves in place the Federal Communications Commission "program access" rules. The ruling marks a setback for Cablevision Systems Corp. and Comcast Corp., the cable companies that had challenged the rules in court.

Comcast has nonetheless pledged to extend those rules to the local NBC and Telemundo stations it would control as part of its proposed combination with NBC Universal. Comcast is seeking FCC and Justice Department approval to buy a 51 percent stake in NBC Universal from General Electric Co.

A former aide to John Edwards is returning to court just days after a North Carolina judge nearly sent him to jail over his handling of a videotape purportedly showing the two-time presidential candidate in a sexual encounter.

Superior Court Judge Abraham Penn Jones scheduled a hearing for Friday. He asked Andrew Young earlier this week to provide a full accounting of how he handled items Edwards' mistress, Rielle Hunter, is seeking.

Judge Jones declared on two occasions during a Tuesday hearing that Young would go to jail for contempt following conflicting statements. But Jones relented after Young's attorneys protested.

Hunter has sued Young for invasion of privacy, seeking the return of items including a tape purportedly showing Edwards and Hunter in a sexual encounter.

Amy Victoria Beck had arrived in court with her lawyer on Wednesday for her arraignment, but it was postponed until March 25.

She is jailed in lieu of $175,000 bail. Her lawyer, Michael Williamson, says she wants to stay there for the time being to avoid the media.

Authorities say Beck arrived at Burbank police headquarters on Monday and said she was tormented with guilt.

Police say she confessed to having sex with one of her male students last year.

Prosecutors charged Beck with five counts, and she faces up to seven years in prison if convicted.
