The New Mexico Senate on Thursday approved a watered-down measure to investigate why nearly $1 billion in infrastructure money remains unspent. Senate Bill 262 next moves to the House with less than two days to go in the 2017 legislative session. The committee in the original bill would have vetted projects that are placed in most annual capital outlay bills by individual lawmakers. But a Senate Finance Committee amendment took away that authority. And a floor amendment restricted the committee to a three-year term.
