Clinton made those comments in, a daily newsletter that concentrates heavily on Washington politics. Clinton also said he thinks that the fact that Congress is allowed to first appropriate funds and then gets a second vote on whether to pay for them is "crazy." The National Memo reports:
Having faced down the Republican House leadership during two government shutdowns when he was president — and having brought the country's budget from the deep deficits left by Republican presidents to a projected surplus — Clinton is unimpressed by the GOP's sudden enthusiasm for balanced budgets. But he never considered invoking the Fourteenth Amendment — which says "the validity of the US public debt shall not be questioned" – because the Republicans led by then-Speaker Newt Gingrich didn't threaten to use the debt ceiling as a weapon in their budget struggles with him.
According to Clinton, the Gingrich Republicans thought about that tactic before rejecting it — and Treasury officials who served under Clinton commissioned legal research on the president's power to raise the debt ceiling without congressional approval. While some legal scholars believe the Fourteenth Amendment requires Congress to fund the debt that results from its appropriations, and therefore empowers the president to raise the debt ceiling, others vehemently disagree.It's Section 4 of the that's in question, if you're curious. That section was brought to light when in May, Treasury Secretary Timothy Geithner pulled out a copy of the Constitution and read the section in question. He said it made using the debt ceiling as a negotiating strategy "not credible."
