PHOENIX (AP) — Gov. Doug Ducey wants to give Arizona voters a chance to abolish a constitutional provision that gives immunity to state lawmakers under some circumstances.

Ducey calls abolition of legislative immunity a "needed reform" and said in a Twitter post Tuesday that he wants lawmakers to act early in 2019 to put a referendum on the ballot.

Ducey last week signed an executive order directing state troopers to cite lawmakers if they break traffic laws despite the constitutional provision.

That order and the proposed constitutional change are reactions to recent disclosure that state Rep. Paul Mosley told a sheriff's deputy who pulled him over that last March he had previously driven at 120 mph (193 kph).

According to a sheriff's report, Mosley said he shouldn't be cited because of legislative immunity.
