President Trump announced Tuesday that he has decided to exit a 2015 six-nation agreement in which Iran agreed to limit its production of nuclear weapons material.

"I am announcing today that the United States will withdraw from the Iran nuclear deal," Trump said.

He said the U.S. will re-impose economic sanctions that were lifted as part of the U.S. commitments made in the deal.

The U.S. has been repeatedly waiving sanctions that curtail Iran's oil sales but those sanctions waivers face a Saturday deadline, prompting Trump's move Tuesday.

Fair housing advocates are suing the Department of Housing and Urban Development to compel it to follow a rule meant to help prevent segregation and comply with the Fair Housing Act. The suit, which also names HUD Secretary Ben Carson, was filed Tuesday morning.

Political ads in Georgia's Republican gubernatorial primary this year may be the most charged of any intraparty battle around the country, especially when it comes to guns.

One ad shows former state Sen. Hunter Hill at a shooting range loading one gun, eyes steady on the camera, and firing another.

"We don't need a carry permit," Hill says, "the only thing we need as Americans is the U.S. Constitution. And as governor, I won't give an inch on our Second Amendment."

Republicans in Indiana and West Virginia will settle two bitter Senate primary fights today, with hopes that the nominees will not be too battered to take down vulnerable Democratic incumbents in November and secure the slim GOP Senate majority.

Candidates in both parties seem to agree on one thing: President Trump is the issue in 2018. While Republicans compete to prove who is most loyal to Trump, Democrats insist it's a tactic that will backfire come November, motivating more Democratic voters than Republicans.

Beef cattle ranchers are getting wise to the science of genetics.

They have always known that making the best steak starts long before consumers pick out the right cut, such as where an animal grazes or what it eats. The key is in the genetic makeup — or DNA — of the herd. And over the past year, those genetics have taken a historic leap thanks to new, predictive DNA technology.

This is playing out in rising auction prices for the best bulls as identified by genetic profiles or simply for their elite pedigree.

As America heads toward the 2018 midterms, there is an 800-pound gorilla in the voting booth.

Despite improvements since Russia's attack on the 2016 presidential race, the U.S. elections infrastructure is vulnerable — and will remain so in November.

Cybersecurity expert Bruce Schneier laid out the problem to an overflowing room full of election directors and secretaries of state — people charged with running and securing elections — at a conference at Harvard University this spring.
