WINDOW ROCK, Ariz. (AP) – Navajo Nation President Ben Shelly once again has vetoed money to fund a commission aimed at developing green jobs.

Shelly says legislation that created the Green Economy Commission doesn't set guidelines on how it would work with the tribe's executive branch, which has similar goals. He also says the commission is supposed to seek outside funding.

Shelly had stripped $353,000 for the commission in September that was included in the tribal budget passed by lawmakers. He cut a proposed $235,000 in funding late last week.

The line-item veto cannot be overturned.

Shelly says he'll work with the commission and lawmakers to establish a green economy.

The commissioners had urged Shelly to approve the funding. They say the tribal government would reap the benefits of combining tribal tradition with modern technology.
