Gov. Jan Brewer will sign what she is calling "historic health care legislation" on Monday in a ceremony to which she has invited supporters who helped get it approved.

The ceremony will be at 11 a.m. in a conference room at the Executive Office Tower, just to the west of the Capitol.

The Legislature on Thursday passed the Medicaid expansion plan as part of the state budget after a contentious five-month session that split the Republican majority, including turning many members of that majority against the GOP governor.

If the legislation itself is historic, then her method of getting it approved verged on history-making in itself.

The strategy she followed from introduction of the idea in her January State of the State speech to passage has been likened to an election campaign. She held rallies throughout the state and built support from a diverse group that brought together business leaders, health practitioners and social welfare advocates.

She also wielded her executive power.

Brewer insisted she would not sign a state budget without Medicaid, and when the Legislature didn't act as quickly as she thought it should, she told lawmakers to stop sending her unrelated bills. When they continued, she vetoed five bills all at once, including some she would otherwise have been expected to sign.

On Tuesday, when the House of Representatives appeared poised to act but instead took a two-day recess, Brewer pounced. She called in eight House Republicans who favored Medicaid, plus House Minority Leader Chad Campbell, D-Phoenix, to discuss what to do.

"How about a special session?" Brewer asked, according to several who were present.

It was already in the works, because within an hour of the meeting, she called the session, putting Republican legislative leaders outside the circle of support, leading to passage of the budget with Medicaid in it, all in less than 48 hours.
