Are there trolls in the Grey Lady's newsroom?

The New York Times (online) has an long article (Registration required. It's free.) about House passage of the energy bill.

The headline: House Passes Energy Bill

But after 19 paragraphs dealing with the energy bill, The Times makes an unexplained shift to a different piece of legislation in the Senate.

Here are paragraphs 19 and 20:

Critics of the energy bill continued to condemn it on Wednesday, saying the tax breaks rewarded oil and gas companies that do not require taxpayer-financed incentives. They pointed to a late addition to the measure that provided $500 million to underwrite research into drilling in deep water or producing gas from unconventional sources.

As the Senate concentrated on legislation to protect gun manufacturers, its passage was virtually guaranteed Wednesday when Senator Bill Frist of Tennessee, the Republican majority leader, used a procedural maneuver to sharply limit efforts by Democrats to amend the bill.

The rest of article continues to report on the gun bill.

What explains the shift from reporting on a House energy bill to a Senate gun bill?
