Rep. Chad Campbell, the minority leader, said he's not opposed to reopening the Grand Canyon with state money. But he said legislators need to make sure it's affordable and that it's not done at the sacrifice of other needs.
"The bottom line is the politicians in (Washington) D.C. need to deal with this — this is getting stupid," said Campbell, D-Phoenix.
