Arizona group joining health care reform fight

Posted: Updated:

A conservative government watchdog group in Arizona is joining the fight against federal health care.

The Goldwater Institute will file a lawsuit challenging the constitutionality of the recent overhaul.

Arizona and 19 others states have already filed suit-- saying the feds can't legally require people to purchase health care insurance.

The Goldwater Institute says its own complaint adds even stronger arguments.

"We believe that there were some arguments that were left on the table and that this is the most sweeping invasion of individual liberty and state sovereignty in our lifetimes, so we have to use every legal resource we can possibly find to bring this law down."
