According to two congressional aides familiar with the dispute, Sen. James E. Risch (R-Idaho) demanded that a provision renaming the White Clouds Wilderness in central Idaho after former four-term governor Cecil D. Andrus, who died last year, be removed from a fast-moving omnibus appropriations bill.

The request generated all sorts complications as Senate leaders sought to clear the 2,232-page $1.3 trillion spending bill ahead of a Friday-night government shutdown deadline. Among them: Changing the bill would require a House vote as well — many hours after the House passed the bill and members left Washington for a two-week recess.

Aides to Risch did not respond to a message seeking comment on his objections. Risch would not comment outside the Senate chamber early Friday morning: “What part of ‘No’ don’t you understand?” he said. “Do I have a problem with my English? I don’t have any comment.”
