ST. PAUL, Minn. — Gov. Mark Dayton signed the law making gay marriage legal in Minnesota, but so far hasn't fielded any invitations to take part in any weddings.

Dayton said Monday that he hasn't been asked to attend or participate in any wedding ceremonies when the new law takes effect next week. That's in contrast to Minneapolis Mayor R.T. Rybak, who plans to officiate 40 same-sex marriages on Aug 1.

Dayton says he doesn't believe he has authority to preside over any nuptials. He says he receives few wedding invitations as it is.

Dayton is scheduled to attend a Gay Men's Chorus concert at Minneapolis city hall on July 31. But he's leaving Minnesota the next morning for a governors' conference in Milwaukee.
