Senator Blocks 850 Promotions In the Air Force
Sen Larry E Craig, Republican of Idaho, blocks 850 promotions in Air Force in effort to get four cargo planes for Idaho Air National Guard; Pentagon officials express outrage that Craig is single-handedly delaying promotions of hundreds of officers and stymying important Air Force business for handful of parochial planes; this is rare clash between senior Republican lawmaker and Pentagon, which vows not to give in to his pressure; Craig contends Air Force reneged on promise made seven years ago to station squadron of eight C-130's at Air National Guard base in Boise; his hardball tactics have angered and frustrated even some Republican colleagues like Sen John W Warner, whose Armed Services Committee approved most of promotions weeks ago; Craig is using Senate practice which allows any senator to block action indefinitely and anonymously on nomination, promotion or legislation; these secret holds are used frequently by senators of both parties, but military promotions are typically whisked through approval process without objection; photos (M)
