John Arnold, the newly appointed executive director of the Arizona Board of Regents, has an affinity for numbers.

State Treasurer Eileen Klein continues to collect a $250,000 a year salary and benefits from the Arizona Board of Regents, even as she is paid as state treasurer.

The Arizona Corporation Commission member has been seeking the seat for more than a year but announced his withdrawal Thursday. He was facing state Sen. Kimberly Yee in August's Republican primary.

Gov. Doug Ducey today tapped former Arizona Board of Regents President Eileen Klein to serve as state treasurer until the November election.

In a statement released Monday, Klein gave no clear timeline for her departure or next moves, saying only that she would be leaving her position later this year “to take some time off before deciding what my next adventure will be.”

Saying they are comfortable with their decision, members of the Board of Regents told Attorney General Mark Brnovich Thursday they have no plans to hike tuition for dreamers -- at least not until the Supreme Court orders them to do it.

With the threat of a lawsuit looming, Attorney General Mark Brnovich wants members of the Board of Regents to explain why they think they can let "dreamers'' pay the same tuition as other Arizona residents.

After months of deliberation, state universities are aiming to admit 200 students in the fall 2017 semester to the Arizona Teacher Academy, a teacher-training program with free tuition.

Regents and lawmakers alike expect the June 18 resignation of the Arizona Board of Regents’ chairman can heal any lingering wounds between them, though Rep. Mark Finchem, R-Oro Valley, who is at the center of the controversy, said the resignation changes nothing.

A little-known policy of the Board of Regents could blunt the financial effect of a new court ruling denying dreamers in-state tuition.
