These days, the Federal Public Defender's Office in Tucson, Ariz., has lots of space. Since the federal budget cuts known as sequestration began, the office has lost a quarter of its staff to layoffs or furloughs.

Under the Constitution, clients still need legal representation, so judges have to appoint private attorneys to replace the public defenders.

The sequester was supposed to save money. But in this case, the sequester is costing federal dollars.

If you like mysteries, thrillers or zombie flicks, you'll probably like Abigail Goldman's art.

Goldman takes the fake grass, dirt and tiny plastic people used in model railroad layouts, and turns them into imaginary crime scenes. She's been making the macabre art for four years, and it's become so popular there's a waiting list for her work.

The Arizona Legislature is debating whether to extend Medicaid to about 300,000 people in the state. The expansion is a requirement to get federal funding under the Affordable Care Act.

The big surprise is who has been leading the charge: Republican Gov. Jan Brewer. She's one of President Obama's staunchest critics and has confounded conservatives in her own party by supporting the expansion.

Google the words "Brewer" and "Obama." You'll get a now-famous image of Brewer wagging her finger at the president on the tarmac last year when she met him in Phoenix.

The runways at Fort Huachuca, Ariz., are busy. This is where the Army tests its military drones, where it trains its drone pilots, and where four Customs and Border Protection drones take off and land.

From here, the CBP drones survey the Arizona-Mexico border — mainly looking for immigrants and drug smugglers.

Some employers around the nation have been using E-Verify to check the immigration status of employees for years. Operated by the Department of Homeland Security, the online system is designed to make it harder to hire unauthorized workers — and harder for those workers to find jobs.

While participation in the program has been voluntary since 1996, the immigration bill now in the Senate would make E-Verify mandatory.

Nearly half the people now in the U.S. illegally didn't climb walls, wade across the Rio Grande or trek through the desert to get here. They arrived legally, with tourist or student visas. And when those visas expired, they just never left.

Like the rest of the 11 million undocumented people in the United States, they are part of the underground economy and the government doesn't know where they are. The Senate immigration bill now before Congress tries to address this problem — though not as richly as it does border security.
