I deny her refutation

If you read the headlines, you might think that Rep. Maxine Waters has refuted charges brought against her by the House Ethics Committee. If you read the actual articles with said headlines, it will turn out that she hasn't really refuted those charges; she has merely denied them. It's a rather significant difference. To refute a proposition that X is to provide evidence and/or argument from which it follows that not-X. To deny a proposition that X is to stick a "not" operator to it. One takes a lot more effort than the other.
