SYRIA The Hill's Julian Pecquet: " UN: Rebels, not Assad, appear to have used chemical weapons" United Nations human rights investigators said Sunday they have gathered testimony from outside Syria suggesting rebels, not Bashar Assad's regime, may have used chemical weapons. LINK

The Washington Times' Tom Howell Jr.: " Israeli airstrikes on Syria put Obama at the crossroads" As Israeli planes hit targets in Syria for the second time in three days, some Republicans on Sunday ramped up their calls for President Obama to take stronger measures against the Assad regime - but the White House response was muted.

BUDGET CUTS The New York Times' Jonathan Weisman: " Stories of Struggle and Creativity as Sequestration Cuts Hit Home" Facing the task of cutting 142 children from the Head Start program in Colorado Springs this fall, the teachers and administrators came up with a creative response: Have the children decorate empty chairs, then sell them for $500 apiece to stave off the worst of the across-the-board federal cuts heading their way. So far, in a month, their "Fill a Seat" fund-raiser has filled just two slots in the program. LINK

The Los Angeles Times' Alexandra Zavis: " Serving their country, losing their jobs" The jobs of the nation's citizen soldiers are supposed to be safe while they are serving their country: Federal lawdoes not allow employers to penalize service members because of their military duties. LINK

CONGRESS ABC News' Benjamin Bell: "Warren Buffett: 'Tough to Watch' Washington Gridlock" During an interview on "This Week," Berkshire Hathaway chairman and CEO Warren Buffett this morning bemoaned the political gridlock in Washington, telling chief business and economics correspondent Rebecca Jarvis that it is "tough to watch." "It's tough to watch what happens in Washington. It's gotten more and more partisan, but now so many elections are determined by the primaries and not the November elections, that it does tend to push both sides to the extremes and to cause them to dig in and feel that they can't bend from positions 'cause they'll get primaried."

Valerie Bauerlein: "Colbert Busch, Sanford Race Is Down to the Wire" The unlikely candidate Elizabeth Colbert Busch, comedian Stephen Colbert's sister, is in a dead heat with former South Carolina Gov. Mark Sanford in Tuesday's special election for a U.S. House seat. Just weeks ago, Mr. Sanford, the Republican candidate, was on track to walk away with the election for the Charleston-based seat, despite leaving the governor's mansion in disgrace two years ago. LINK

Politico's David Nather: " Behind the immigration rhetoric" Congress returns to Washington Monday with a key immigration question still up for debate: what's it going to cost? It's an issue that's rippling through the broader debate and is sure to be on display when the Senate Judiciary Committee begins work on the Gang of Eight's bill and other committees hold hearings on immigration and the economy, high-skilled visas policies and border security this week.

GUN CONTROL USA Today's Gregory Korte: "New NRA leader says Obama seeks 'revenge' on gun owners" The board of the National Rifle Association will elect as its president Monday a hard-line culture warrior who has worked for decades to make the NRA a more aggressive political force. The election of James Porter - ensured after the endorsement of outgoing President David Keene last week - is one of many defiant signals to come out of the NRA's annual meeting in Houston over the weekend.

OTHER The Washington Post's Cheryl W. Thompson: " Obama tells Ohio grads: 'America needs full-time citizens'" President Obama urged the graduating class of Ohio State University on Sunday to take an active role in guiding the future of democracy in the United States and to fight for the issues that the new graduates care about. "There's a word for this," he said. "It's citizenship. .?.?. Sometimes we see it as a virtue from another time." LINK
