The present Syrian crisis ranks among the most vexing moments of President Obama's presidency.
The recent heart-rending images of Syrian civilians, many of them young children apparently killed by chemical weapons used by the government of Bashar Assad, have raised the volume on calls for the president to act.
But while there's a clarity to the outrage itself, for Obama things quickly get murky.
Fifty years ago this week, when hundreds of thousands of demonstrators came from across the country to take part in the 1963 March on Washington, the city was not yet the cosmopolitan capital that it arguably is today.
But it was a mecca for African-Americans, says historian Marya McQuirter.
"Washington was definitely a different city 50 years ago," she says, "for a number of reasons. By 1957, it had become the largest majority black city in the country."
"I didn't do this to do any hating on anyone. I did this to be funny. I did it to be a joke," says Tuffy Gessling, the rodeo clown behind a skit at the Missouri State Fair earlier this month that sparked outrage when a masked "President Obama" was chased by a bull that Gessling said was "gonna getcha, getcha, getcha, getcha!"
The nation is marking the 50th anniversary of the historic March on Washington this week. Tens of thousands traced the path of civil rights leaders and foot soldiers in the nation's capital this weekend. On Wednesday, President Obama will speak from the Lincoln Memorial, just as Dr. Martin Luther King Jr. and other speakers did back in 1963. Tell Me More reflects on the role political activism played and is continuing to play in the civil rights movement.
If you're looking for the most interesting gubernatorial races to watch in the coming year, the nation's biggest states are a good place to start.
Democrats Jerry Brown and Andrew Cuomo look like safe bets for re-election in California and New York, respectively. And, despite the pending retirement of Rick Perry, Republicans are confident of maintaining their hold on the governor's mansion in Texas.
Tens of thousands of people assembled on the National Mall to commemorate the 50th anniversary of Martin Luther King Jr.'s 1963 March on Washington, best known as the venue for the iconic "I Have a Dream" speech that helped galvanize the civil rights movement.
Organizers, including the Rev. Al Sharpton and King's son, Martin Luther King III, had hoped to attract 100,000 people to attend Saturday's events leading up the official Aug. 28 anniversary.
Last month, Kentucky Democrat Alison Lundergan Grimes declared she'll run against minority leader, Mitch McConnell for the U.S. Senate.
ALISON LUNDERGAN GRIMES: ...Kentucky by running for the U.S. Senate.
SIMON: Her candidacy had been rumored for months. The obvious Web domain name, Grimesforsenate.com, had already been purchased. But not by the Grimes' campaign. By a man who's a kind of political hobbyist.
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.
