Just two days before the National Rifle Association's annual convention in Phoenix, the state House of Representatives gave its approval to a measure that would allow gun owners to keep weapons in their cars, even if it is against a private property owner's wishes.

The House will decide today whether to give a preliminary endorsement of a letter to Congress stating Arizona's concern that federal greenhouse gas regulation will hurt the state's economy.

A bill being considered by Arizona legislators is seen as pitting the rights of gun owners against the private property rights of businesses and others.

Uncertainty looms over all non-budget bills in the Legislature, and no one knows when, or if, lawmakers will have time to address issues such as a proposed one-year moratorium on state agency rulemaking.

The biggest differences between the Republican budget proposal released April 27 and a draft leaked to the press a month earlier were two components designed to generate more than $500 million in revenue without raising taxes. And those two ideas have created the biggest backlash against the latest proposal.

A House panel could be considering a proposal to solve next year's $3 billion budget deficit as soon as April 28, a top Republican said.
