Not insulting... "weasel words" are demonstrative of his soft backpedalling stance.
A weasel word, or anonymous authority, is an informal term for words and phrases aimed at creating an impression that a specific or meaningful statement has been made, when instead only a vague or ambiguous claim has actually been communicated. This can enable the speaker to later deny the specific meaning if the statement is challenged. Where this is the intention, use of weasel words is a form of tergiversation.
Weasel words can be used in advertising and in political statements to mislead.
Weasel words can soften or under-state a loaded or otherwise controversial statement, for example by using the detensifiers "somewhat" or "in most respects".[1]
