International Monetary Fund officials and members of the G-20 nations announced Friday that member countries have pledged $430 billion to add to the Fund's crisis-fighting arsenal.

The Fund's managing director Christine Lagarde came into the annual World Bank-IMF spring meetings in Washington, D.C., with a goal of raising $400 billion from member states. She was clearly happy and relieved as she announced a number larger than that.

It's been two years since the Deepwater Horizon exploded in the Gulf of Mexico, killing 11 rig workers and unleashing the worst oil spill in U.S. history. The oil has long stopped flowing and BP spent billions of dollars to clean up oiled beaches and waterways, but the disaster isn't necessarily over.

Oil fouled some 1,100 miles of Gulf Coast shoreline, but today, in most spots, you can't see obvious signs of the spill. In Orange Beach, Ala., the clear emerald waters of the Gulf roll onto sugar-white sand beaches.

Update at 6:19 p.m. ET. Three Secret Service Agents Step Down:

The Secret Service confirmed that three "additional employees have chosen to resign" and a twelfth employee has been implicated.

"At this point, five employees continue to be on administrative leave and their security clearances remain suspended pending the outcome of this investigation," the agency said in a press release.

The three dismissals today brings the total number of agents forced out of the agency because of the scandal to six.

The World Health Organization is telling couples around the world to get tested together to see if either is infected with HIV.

If one of them is, that partner should start treatment with anti-HIV drugs – even if it's not yet medically necessary.

A North Carolina judge commuted the death sentence of convicted murderer Marcus Robinson saying racial bias tainted his trial and sentencing. Instead, Robinson will serve life in prison.

The latest financial numbers are coming out Friday from the campaigns of President Obama and Republican presidential candidate Mitt Romney — along with the superPACs that love them.

First, the easy numbers: $53 million was raised in March to re-elect Obama and $12.6 million was raised by the Romney campaign to win the Republican primaries.

But those easy numbers don't give a complete picture.

In the early 1990s, The Education of Little Tree became a publishing phenomenon. It told the story of an orphan growing up and learning the wisdom of his Native American ancestors, Cherokee Texan author Forrest Carter's purported autobiography.

This week, music is bringing Americans and Russians together in a way that policy discussions never can. And don't call that a cliche in front of the music director of the Chicago Symphony Orchestra.

If U.S. relations with Russia have hit a sticky patch over Syria and other issues lately, that didn't stop the Chicago Symphony from thrilling a Russian audience this past Wednesday night, just as it did on its last visit — to the then-Soviet Union in 1990.

In Myanmar, there are signs in the most unlikely places that people are starting to believe recent political reforms are for real, and aren't just a trick.

Take a recent performance of the Moustache Brothers vaudeville troupe in the northern city of Mandalay.

The troupe performs in the family home — it's not allowed to perform in public. Its biting political satire, aimed at the generals and their cronies, has made the troupe a favorite of Western tourists and diplomats.

Melissa Block speaks with our regular political commentators, E.J. Dionne of The Washington Post and Brookings Institution, and David Brooks of The New York Times.

If the rule of threes holds, it's a strange time to be a U.S. governor. From bears in bird feeders to snoozing to Springsteen, Melissa Block recounts a trio of oddball things governors from Vermont, North Dakota and New Jersey have had to deal with in the last week or so.

Republicans and Democrats don't agree about much on Capitol Hill these days, but there is one bill gaining bipartisan support. It's legislation that would punish human rights violators in Russia by naming them and denying them visas to the U.S. But the Obama administration is not on board yet. U.S. diplomats worry it could complicate relations at a time when the U.S. needs Russia's support most.

If diet is destiny, then modern humans should thank our ancestors for their ability to eat just about anything.

Two new studies peek into the distant past to try to figure out just how big a role food played in human evolution. One says that eating meat made it possible for early human mothers to wean babies earlier and have more children.

A Dutch virologist is considering his full range of legal options if his government refuses to lift the restrictions it has put on his controversial bird flu research, and matters could quickly come to a head after a meeting next Monday that will be attended by U. S. observers.

Of Monsters and Men is an Icelandic sextet specializing in catchy folk-pop. The group came together in 2009 when singer Nanna Bryndís Hilmarsdóttir began recruiting backups for her acoustic solo act. In 2010, Of Monsters and Men gained national fame when it won an annual Icelandic battle of the bands; since then, the buzz has only grown.

There's another bit of tragic news to report today: 43 people are dead after a truck crashed into a passenger bus in eastern Mexico today. Authorities told the AFP that the incident happened after a trailer came loose and hit a bus carrying agricultural workers headed to work.

The AP reports:

Smoking is bad. Quitting smoking is hard. But exercising can make quitting easier, and make sliding back into smoking less likely.

That's the word from a big new study, which tracked the health and habits of 434,190 people in Taiwan from 1996 to 2008. Smokers who got just 15 minutes of exercise a day were 55 percent more likely to quit than were people who weren't active at all. And those active smokers were 43 percent less likely to relapse when they did quit.

A story and two questions on the New York state English exam taken by eighth-graders this week has stumped many — including Jeopardy! star Ken Jennings.
