Energy legislation remained in limbo Friday, stalled by tight vote counts, partisan squabbling and fresh veto threats from the White House. Floor consideration was likely to be delayed until Saturday at best.

Democrats at midday were considering making changes to the energy tax package (HR 2776) to placate oil-state Democrats upset about treatment of the oil and gas industry.

There “may be some slight changes,” said John B. Larson, D-Conn., vice chairman of the Democratic Caucus, after a meeting in the office of House Speaker Nancy Pelosi, D-Calif. Larson would not elaborate on what the changes might be, but Democrats have been struggling to ensure that they can muster a majority vote in support of the energy package. They cannot count on support from many, if any, Republicans.

House Democratic leaders still insist the chamber will take up the energy tax bill and a broader energy measure (HR 3221) before it leaves for the monthlong August recess. The Rules Committee was expected to draft a rule later Friday, with floor votes Saturday. But even that could prove optimistic.
