Arizona Gov. Jan Brewer won a battle with state lawmakers this week, defying most other conservatives in her party to get a key component of President Obama's Medicaid expansion through the Legislature.
The Arizona Senate voted Thursday to approve the measure 18 to 11. That followed approval earlier this week by the state House of Representatives.
The issue had inflamed passions and divided the Legislature for weeks. Things came to a head Tuesday when Brewer called lawmakers into the Capitol in Phoenix for a surprise special session.
