The Note: Who Stood With Rand This Time?

— -- NOTABLES

--WHAT TEAM RAND IS SAYING: "Because of Senator Paul's ten and a half hour filibuster, the Senate adjourned late last night without moving to proceed to the reauthorization of the Patriot Act."

--TODAY ON THE TRAIL with ABC's CHRIS GOOD: The latest GOP cattle-call will start today in Oklahoma City, where the Southern Republican Leadership Conference will see speeches from 11 Republican contenders between now and Saturday. Today, we'll hear from Scott Walker, Rick Santorum, and Rick Perry (plus Reince Priebus and Gov. Mary Fallin).

WHAT WE'RE WATCHING

THE BUZZ

with ABC's VERONICA STRACQUALURSI

HERE'S HOW CRAZY IT GETS WHEN HILLARY CLINTON AVOIDS THE MEDIA FOR A MONTH. After 28 days of not taking questions from the press, Hillary Clinton finally did on Tuesday -- even answering a question about not answering questions! -- and the spectacle that ensued overshadowed any answer she actually gave. ABC's LIZ KREUTZ gives us an inside look the bike shop in Cedar Falls, Iowa, when Clinton walked over to her (pent up) press corps for the first time in four weeks. http://abcn.ws/1ScZTfE

WHY WASHINGTON IS ARGUING OVER CUBA'S AIRBNB PROLIFERATION. Both criticism and praise were bipartisan yesterday in a Senate hearing over the Obama administration's normalizing of relations with Cuba, as a new round of diplomatic discussions between senior officials from both countries is set to begin Thursday. The hearing touched on everything from reported political detentions by the Castro regime since negotiations began, to Airbnb, a website where users can post private rental accommodations, used by many Cubans recently, ABC's ALEXANDER MALLIN reports. GOP 2016 presidential contender Sen. Marco Rubio, who has hardly been shy in his opposition to the negotiations, said he was mainly opposed to the idea that any tourist dollars from Americans who gain the ability to visit would go to the Cuban military. "In essence, when you travel to Cuba and stay in one of these hotels, not only are you putting money in the hands of the Cuban government, you're trafficking in stolen goods," Rubio said. http://abcn.ws/1HtX5om

TERROR FILES: WHAT'S ON OSAMA BIN LADEN'S BOOKSHELF.' The U.S. government Wednesday released dozens of documents recovered from the special operations raid that killed al Qaeda leader Osama bin Laden, including now declassified material and 39-English language books. The Office of the Director of National Intelligence released the documents online yesterday, calling them "Bin Laden's Bookshelf," after what it called a "rigorous interagency review" in an effort to "align with the President's call for increased transparency..." The material includes think tank reports, software and technical manuals for computer programs, and Arabic-language letters to bin Laden's apparent associates, including other suspected terrorists wanted by the U.S. ABC's LUIS MARTINEZ and LEE FERRAN have more. http://abcn.ws/1R3gIrQ

CAPITOL POLICE OFFICERS GET BATHROOM TRAINING AFTER LEAVING FIREARMS IN RESTROOMS. U.S. Capitol Police Chief Kim Dine says his officers are receiving potty training (get it?) after three separate incidents this year when officers left firearms unattended in the Capitol's public restrooms. "We are now providing additional training on what to do when you have to go to the bathroom," Dine told lawmakers during a hearing Wednesday, ABC's JOHN PARKINSON writes. Dine said a first-time offender would be suspended for five days under current policy for leaving a weapon unattended, but he is considering toughening the penalty to 30 days or even potential termination for a first offense because of the seriousness a single error can carry. "There are no excuses for these mistakes," he stressed. http://abcn.ws/1IQdOUn
