I found it interesting that three lawmakers who were defeated for re-election or didn't seek re-election still got a fair amount of out-of-state travel. Nothing illegal about that -- the Legislative Council voted unanimously to allow it. All three legislators in questions were officers of the national organizations putting on the events or members of committees for those organzations.
The lawmakers who go on these trips insist that the educational value is high and the state benefits from the information and ideas that are shared. Critics question why taxpayers should spend the money to "educate" lame-duck legislators who won't be coming back to next year's session.
There's some lists of who traveled the most, top destinations and travel costs for Santa Fe legislators (which wasn't very much) HERE
