CHEYENNE, Wyo. (AP) — Wyoming's congressional delegation is critical of warnings from the Obama administration about how budget cuts could affect operations in national parks including Grand Teton and Yellowstone.

Sens. Mike Enzi and John Barrasso and Rep. Cynthia Lummis accuse the Obama administration of engaging in scare tactics when it comes to the effects that steep budget cuts could have on national parks.

A report just out from the National Park Service says Yellowstone and Grand Teton sustain thousands of jobs and draw hundreds of millions of dollars in economic activity to surrounding communities every year.

Recent leaked memos specify how steep budget cuts could affect national parks. In Yellowstone, delayed plowing could cause roads to open later than usual this spring. In Grand Teton, the Jenny Lake Visitor Center could be closed.
