President-elect Donald Trump is expected to name former Georgia Gov. Sonny Perdue as his nominee for agriculture secretary, according to a transition official and a source close to the process.

This is the last open Cabinet position, although Trump has yet to name a Council of Economic Advisors chair, which is a Cabinet-level position.

The process of selecting an agriculture secretary turned into a marathon, as Trump interviewed many candidates.

Perdue was a favorite among major farmers' groups and leaders in the Republican establishment.

Three baseball stars who avoided convincing connection to steroid use during their playing days — Jeff Bagwell, Tim Raines, and Ivan Rodriguez — were elected to Major League Baseball's Hall of Fame Wednesday. The stars all received 75 percent of the ballots cast by the Baseball Writers Association of America.

Scott Pruitt, Donald Trump's pick to head the Environmental Protection Agency, underscored the importance of federalism in U.S. environmental policy and regulation, and criticized the agency he's being tasked to run, at his confirmation hearing Wednesday.

The Oklahoma attorney general vowed to follow the "rule of law," if confirmed, and promised to "fairly and equitably enforce the rules and not pick winners and losers."

Episode 748: Undoing Obama

There is this race going on right now in Washington D.C. The finish line is Friday at noon--inauguration day. The desperate runners are all the people who work for Barack Obama. They're rushing to do everything they can to cement the legacy of this president before the next one takes office.

The way they are doing this: Rules. Congress may pass the laws, but the president and the agency heads he appoints write the rules. And it is the rules that dictate how laws play out in our daily lives--how strong a regulation will be, and even who gets funding.

It took years of heated debate, but the federal government has finally decided just how much living space an organic chicken should have.

It's part of a new set of rules that cover many aspects of animal welfare in the organic food industry. But the biggest impact of the rule will be felt in the organic egg industry.

State authorities say Virginia has executed a man who was sentenced to death for murdering two children.

The execution of Ricky Gray by lethal injection is the first known instance of any state using a dose of the sedative midazolam that was procured from a compounding pharmacy rather than a pharmaceutical company, according to the Death Penalty Information Center.

Among the many things President Obama will be handing off to his successor this week: stubborn wars in three separate countries.

Obama came to office eight years ago vowing to end U.S. military interventions in Iraq and Afghanistan. Yet President-elect Trump stands to inherit the nation's longest war ever in Afghanistan, as well as renewed fighting in Iraq that has spread to Syria.

The Obama administration has dropped a controversial proposal that would have required all federally funded scientists to get permission from patients before using their cells, blood, tissue or DNA for research.

One of the big questions about extensively drug-resistant tuberculosis is whether this severe form of the disease is on the rise due to a failure of medications or if it's spreading through the air.

A new study of more than 400 patients in South Africa finds, unfortunately, that the answer appears to be the latter. Airborne transmission is the driving force behind a spike in extensively drug-resistant tuberculosis (XDR-TB) in South Africa, according to a report just published in the New England Journal of Medicine.
