I tried to find a Bill number for anything to do with the actual deployment of troops to Kuwait and came up empty-handed. And there probably never was a specific Resolution that dealt with troops being sent there, since the deployment was ordered when Congress was on summer vacation, and few knew about it until after the fact.
I found an August 19, 1990 New York Times article titled: "Largest U.S. Force Since Vietnam is Committed in a 15-Day Flurry" by Michael Wines. Here is an excerpt dealing with McCain's comments:
"Most public figures scrambled to support the President's decision, but a handful of supporters like Senator John McCain, an Arizona Republican who is on the Armed Services Committee, have begun raising the first caution flags about the operations."
"I think we'll stand it for a long period of time, as long as there are not casualties," Mr. McCain said in a telephone interview from Arizona. "If you get involved in a major ground war in the Saudi desert, I think support will erode significantly. Nor should it be supported. We cannot even contemplate, in my view, trading American blood for Iraqi blood."
I apologize because the information I had was wrong about a specific deployment vote. I have read elsewhere that he was against sending ground troops in, but supported air strikes in their place. He was also against going into Baghdad and finishing the job in '90.
