Nice collection of quotes at Glenn Greenwald’s blog Unclaimed Territory from Republican senators back in October 1993 as they forced Clinton to withdraw U.S. troops from Somalia.
Of course, that was back when the Constitution gave Congress the authority to mandate a withdrawal; nowadays, as some of those same Republican senators are currently arguing, our Constitution gives that authority only to the president.
For example, Sen. John McCain said back then:
What is the criteria and what should be the criteria is our immediate, orderly withdrawal from Somalia. And if we do not do that … then I would say that the responsibilities for that lie with the Congress of the United States who did not exercise their authority under the Constitution of the United States and mandate that they be brought home quickly and safely as possible ….
