Syria: The Red Line Zone - Literally during opening of George W. Bush Presidential Library today came word that US believes - with a "reasonable amount of confidence" - that Syria used chemical weapons. http://abcn.ws/14SH2Ra

That means the red line is crossed, right?

John McCain, Lindsey Graham, Dianne Feinstein and John Boehner all say yes. The Obama administration isn't quite ready to go that far. They want to examine the chain of custody for samples that suggest chemical weapons, reports Alex Marquart and Mary Bruce.

Hagel argued today that is it unclear whether the red line has been crossed and said more evidence was needed.

"We need all the facts. We need all the information. What I've just given you is what our intelligence community has said they know," he said. "They are still assessing and they are still looking at what happened, who was responsible, and the other specifics that we'll need."

McCain said the red line is behind us. What should come now, he said, per Sunlen Miller, is some sort of action.

"The president of the United States said this would be a red line if they use chemical weapons," said McCain. "The president of the United States has now told us that they used chemical weapons. Those stocks of chemical weapons, some of which are in disputed areas, must be secured and we must give the opposition the capability to drive out Bashar al-Assad once and for all. And our relations with Russia should be directly related to their assistance to Bashar al-Assad which is significant." http://abcn.ws/12oNKd1

Train Wreck? The Obamacare Unknown - It has been a little more than three years since Obamacare was signed into law, and it is still 251 days until the majority of the law kicks in. After that, nobody really know what's going to happen. One senior Democrat recently predicted a "train wreck" unless the Obama administration does a better job explaining how things are going to work. The one thing that everyone knows for sure is that the law is complicated. Republicans have assembled a seven-foot tower of paper to represent all of the regulations and rules that will go along with the law. Americans still don't really understand or like the law. But they don't want to get rid of it. Republicans no longer agree that the law should be repealed. But even Democrats are publicly nervous about what happens when the law finally takes effect and people have to buy insurance or pay a tax. What lies at the end of the line on Jan. 1, 2014? A " train wreck" if you ask Sen. Max Baucus, a key author of the law who helped dash progressive dreams of a more liberal overhaul. http://abcn.ws/12oNKd1

70 Votes for Immigration Reform - Jordan Fabian reports on McCain and Schumer's joint appearance today : "Maybe this is hopeful, but it would be wonderful if we could get a majority on both sides," Sen.

John McCain, R-Ariz., a top Republican in the "Gang." abcn.ws/ZvsYd3

Obama: Thank Bush If Immigration Passes-One major piece of unfinished business from George W. Bush's presidency is comprehensive immigration reform.

Perspective Piece: - For George W. Bush Legacy, 'Compassionate Conservatism' is Back- With the George W. Bush Presidential Center opening today, the former president and his team are moving back to the beginning in seeking to shape the legacy of their four years in office. Meet George W. Bush, compassionate conservative. Again. Though it's easy to forget in a presidency that saw 9/11, two wars, Hurricane Katrina and a financial crisis, "compassionate conservatism" was the philosophy Bush used to first define himself on the national stage. He defined it as insisting on "responsibility and results," coupled with an obligation to help "citizens in need." http://abcn.ws/13xSLzW (Rick Klein)

Barbara Bush Votes 'No' on Jeb Bush for President- If mother truly knows best, there will be no more additions to the Bush presidential legacy. Bush family matriarch Barbara Bush said she's not in favor of a 2016 presidential run by her youngest son, Jeb Bush. "There are other people out there that are very qualified and we've had enough Bushes," she told NBC's Matt Lauer. Jeb Bush has not said if he will seek the presidency. "He'll get half of our friends and all of our enemies," she added, referring to the possibility of family baggage getting in the way of a successful 2016 presidential candidacy. http://abcn.ws/15JvbnY (Alisa Wiersema)
