Last week, 12 Republican congressmen, including DuncanHunter, the Californian who is chairman of the House Armed ServicesCommittee, signed a letter to Defense Secretary Donald H. Rumsfeld,raising pointed questions about his policy of allowing journalists totravel with American troops. The congressmen said journalists -- specifically Peter Jennings,the ABC News anchor -- were asking soldiers 'inappropriate' ques-tions, like what anxiety they had about fighting. The congressmenasked Mr. Rumsfeld to explain why he was not imposing 'censor-ship.'
