And to whomever said it was political and not halachic, how is it appropriate to make political statements at someone’s wedding, when that someone probably chose the eidim beforehand and now you go ahead and decide to jettison that pick?
Personally, I think that it is within the MK’s rights to do so. Whether it’s appropriate to do so is another question.
And certainly, such issues should have been clarified well before the wedding, to avoid potential embarrassments and to give the couple a chance to find another MK if they absolutely wanted this person as a witness. The couple should have been given the option ahead of time. At the wedding is not the appropriate time to start making non-halachic* (i.e. personal/political) objections.

* I was at a wedding once where the couple called up the bride’s brother-in-law as a witness. That’s an example of a *halachic* objection (since he’s ineligible).
