In a rare departure from tradition, Saturday's weekly presidential address was delivered not by President Obama but instead by Francine Wheeler, whose son Ben, 6, died in the Sandy Hook Elementary School shootings last December.

Flanked by her husband, David, Wheeler called for Americans to urge the Senate to pass gun control legislation that it is scheduled to begin debating in the coming week.

Bitcoin, the digital currency that trades outside the control of central banks and international borders, reached new heights Tuesday, surpassing the $200 mark for the first time.

Bitcoin's rise has been sharp. It was only two months ago that exchange rates put a single bitcoin's value at around $20.

The person behind the elaborate online hoax in which a fake website and Twitter feed falsely proclaimed Pastor Joel Osteen's intent to renounce Christianity and shut down his influential Houston ministry says that his goal wasn't to attack Osteen personally.

"I would like to state unequivocally my intent was not to defame Mr. Osteen," the person behind the hoax wrote in an email, adding that "he seems like an infectiously nice and genial character."

April Fool's Day was one week ago — but an elaborate hoax targeting Pastor Joel Osteen gained wide attention Monday, after those behind the hoax used Twitter, YouTube, and other social media to spread spurious claims that the pastor had renounced his faith and would close his huge Texas church.

Convicted murderer Gary Haugen has spent more than 30 years in prison; he's been on death row since 2007. And if he had his way, he would schedule his execution tomorrow. But in an unusual case, the Oregon Supreme Court must decide whether Haugen, who has waived his right to appeal, can die — or if Gov. John Kitzhaber's reprieve of Haugen should stand.

A meteorite that lit the sky over Sri Lanka with a yellow and green flame when it fell to earth on Dec. 29, 2012, contains "fossilized biological structures," according to researchers in Britain, Sri Lanka, and the United States.

A week after a sweeping and controversial education bill was adopted by the Alabama Legislature, the measure is on hold, with a circuit judge and the state's supreme court reviewing separate lawsuits filed over it. Democrats say Republicans broke the rules when they inserted school choice language into a bill that was originally meant to give school districts flexibility in meeting standards.

When he was arrested for driving under the influence of alcohol and other charges in 2005, Stephen Slevin had no way of knowing that an opinion about his mental state would put him on a path to spend more than 22 months of solitary confinement in a New Mexico county jail, despite never having his day in court. This week, he reached a $15.5 million settlement with Dona Ana County.

Arkansas has approved a law banning most abortions after 12 weeks of gestation, as both houses of the state's legislature vote to override a veto by Democratic Gov. Mike Beebe. The Republican-backed Human Heartbeat Protection Act will become the nation's most restrictive law.

In vetoing the Senate version of the bill Monday, Beebe said that it "would impose a ban on a woman's right to choose an elective, nontherapeutic abortion well before viability."

The attack resulted in an estimated 30 deaths and 300 injuries. Khan, a naturalized U.S. citizen, could face a maximum sentence of life in prison if he is found guilty. FBI agents arrested him at his home Tuesday morning.

William Moody, who as the pro wrestling character Paul Bearer embodied a sense of theater that was equal parts morbid and absurd, has died at age 58. A portly man known for his wild-eyed stare and habit of carrying a brass urn under his arm, Paul Bearer was most notably the manager of The Undertaker and Kane.

A judge in Alabama has blocked the state's governor from signing a school choice bill, after a lawsuit alleged that lawmakers bypassed state rules when they substantially revised the legislation in committee. The vote to pass the bill last week was marked by confusion, anger, and accusations of "sleaziness" and "hypocrisy," as AL.com reported.

Here was the scene last week, as the bill's backers sought to end debate and hold a vote:

The Masters Tournament is still a month away, but the green jackets that grace the winners' shoulders are already in the news, thanks to a lawsuit over a proposed auction of a former champion's jacket.

On one side is tournament host Augusta National Golf Club, which says the jacket, won by Art Wall Jr. in 1959, was stolen; on the other is Florida doctor Stephen Pyles and Heritage Auctions of Texas, who insist the jacket was obtained legally and can thus be sold to the highest bidder.

Days after angering cyclists with his contention that people who ride bikes don't help pay for roads — and stating that "the act of riding a bike results in greater emissions of carbon dioxide from the rider," Washington State Rep. Ed Orcutt has apologized for his words, and any confusion they created.
