2:03 p.m. ET: "I have to tell you I’m happy today, I hope you’re happy today," Romney says at his campaign rally in Ashland, Virginia to cheers. "I know that the Democrats are working very hard today. They're pulling out all their books and they're looking at every vote and they're interviewing everybody in his neighborhood. They're not going to find anything."
1:58 p.m. ET: Ryan lists Romney's credentials, including leadership of the 2002 Olympics and governorship of Massachusetts, and criticizes Obama's tenure in office. "We’ve seen that hope and change has become attack and blame," under Obama, Ryan said.
1:54 p.m. ET: "We’re at that proverbial fork in the road. We have the choice of two futures ahead of us," Ryan at a campaign rally in Ashland, Virginia.
1:52 p.m. ET: Romney and Ryan are taking the stage at a campaign rally in Ashland, Virginia.

1:40 p.m. ET: Sunday on a special two-hour edition of CNN's State of the Union, Candy Crowley looks at Romney's running mate selection, his swing state bus tour, and the nasty campaign ads - more than 10,000 of them this month alone - hitting those battleground states. Read more
1:28 p.m. ET: The Obama campaign released a statement saying Vice President Joe Biden called Ryan "earlier today to congratulate him on his selection and welcome him to the race. The Vice President urged Congressman Ryan to enjoy the day with his family, and said he looked forward to engaging him on the clear choice voters face this November."
1:24 p.m. ET: CNN's Chris Welch reports that former Minnesota Gov. Tim Pawlenty, who was considered to be on Romney's short list, said in Manchester, New Hampshire Ryan is "a bold leader with great ideas for trying to get this country back on track, and I think he and Governor Romney together will make a great team."

1:21 p.m. ET: Romney, Ryan, and Virginia Gov. Bob McDonnell stopped at "Homemades by Suzanne" in Ashland, Virginia where the candidate bought $60 worth of pies. Suzanne's website advertises "Whole Deep Dish Pies, Jumbo Cookies, House-made Rolls, Cream Puffs, Shrimp, Chicken, Tuna, & Country Ham Salad by the pound, and many other salads, soups and desserts."
1:14 p.m. ET: CNN's Jim Acosta reports "in the conservative movement, there is arguably no bigger gun than the GOP's presumptive vice presidential nominee." Full Story

12:49 p.m. ET: The t-shirts are printed...
12:43 p.m. ET: Andrea Saul, Romney's campaign press secretary, wrote on Twitter that fund-raising was spiking for the candidate after revealing Ryan as his running mate.
In July, Romney's campaign and the RNC raised $101.3 million - an average of $3.4 million per day. Most of that, however, was raised at high-dollar fund-raisers.
12:35 p.m. ET: Former President George W. Bush issued this statement, distributed by Romney's campaign:
"This is a strong pick. Governor Romney is serious about confronting the long-term challenges facing America, and Paul Ryan will help him solve the difficult issues that must be addressed for future generations."
12:26 a.m. ET: Republicans are piling praise on Romney for his choice of Rep. Ryan as his running mate. One prominent name yet to weigh in, however, is the 2008 GOP vice presidential nominee Sarah Palin.
Democrats are also reacting, slamming Ryan for his budget plan and tax proposals.
12:16 p.m. ET: CNN Senior Producer Kevin Bohn writes that picking Ryan was a "bold but risky choice" for Romney.
"Rep. Paul Ryan admits that he is the poster child for controversial proposals to reform the nation's entitlement programs: For workers now under the age of 55, seniors would be given the option of choosing a private program instead of the traditional Medicare program and would receive money to offset the premium they have to pay. Federal spending for Medicaid would be sent to the states to manage, and the Social Security retirement age would gradually be raised to 70."
Another analysis, from New Yorker Washington Correspondent and CNN Contributor Ryan Lizza: "Romney has made the most daring decision of his political career. After spending weeks looking into Ryan’s history for The New Yorker, visiting his home town, and interviewing him twice, I am genuinely surprised that Romney chose him."

10:41 a.m. ET: Perspectives from around the web on Romney's pick of Ryan as his running mate:
Julian Zelizer on CNN.com: "The decision excites many conservatives who have been calling on Romney to go big. They believe Ryan will inject some juice into a campaign they feel has been lackluster and put the focus on the policy differences between Romney and President Obama."
John Podhoretz at Commentary Magazine: "The speech vice-presidential candidate Paul Ryan delivered this morning gives a sense of the quality you get from being in a room with him: He’s not a fire-breather."
Wendell Potter on iWatch News: "If Americans who are embracing Rep. Paul Ryan’s “Path to Prosperity” — and that now includes Mitt Romney — spent a few minutes reviewing a few recent research reports, they just might conclude that the Wisconsin Republican’s plan to reduce the deficit might better be renamed the “Path to the Poorhouse” because of what it would mean to the Medicare program and many senior citizens."
Paul Begala at the Daily Beast: "With Ryan, Romney Has the Plutocrat Ticket"
10:25 a.m. ET: More from Beth Myers, who led Romney's search for a running mate. She spoke exclusively with CNN Chief Political Analyst Gloria Borger.
10:21 a.m. ET:
10:18 a.m. ET: President Barack Obama's campaign already has a webpage in place tearing apart the newly formed GOP ticket.
"Paul Ryan and Mitt Romney both support trillions in budget-busting tax cuts for millionaires that will result in tax hikes on the middle class and deep cuts in education and other investments we need to grow," the page begins.
Responding to the Democrats' attacks on Ryan, House Majority Leader Eric Cantor said on CNN: "It's nothing but smear tactics, once again, because President Obama doesn’t want ot talk about his economic record."
10:14 a.m. ET: What has Obama said about Ryan's budget plan? He slammed it in April, calling it "thinly-veiled Social Darwinism."
"It is antithetical to our entire history as a land of opportunity and upward mobility for everyone who's willing to work for it - a place where prosperity doesn't trickle down from the top, but grows outward from the heart of the middle class," Obama said.
10:11 a.m. ET: Beth Myers, who led Romney's search for a running mate, told CNN Chief Political Analyst Gloria Borger that Romney is "very methodical in making his decisions."
"What he wants is a couple things," Myers said. "First of all, he wants all the information, and we went about a very thorough process in making sure we had a lot of information about a broad group. He also doesn't like to rule anything out until he has to."
10:07 a.m. ET:
10:06 a.m. ET:
10:05 a.m. ET: Beth Myers has long been Mitt Romney's most trusted political adviser, so it's no surprise that he tasked her with the job of helping him find the right running mate
In an exclusive interview with CNN earlier this week, Myers described to CNN what the process entailed.
10:00 a.m. ET: Romney's slip-up when he introduced Ryan as "the next president of the United States" isn't the first time a presidential candidate made that mistake. Then-candidate Obama introduced Joe Biden in 2008 by saying "So let me introduce to you the next president - the next vice president - of the United States of America, Joe Biden!"
9:58 a.m. ET: CNN Political Reporter Peter Hamby points to a similarity (at least in campaign stops) to the 2008 and 2012 VP picks.
"Next stop for Paul Ryan? Homemade's By Suzanne in picturesque downtown Ashland, Virginia (outside Richmond). Why does that sound familiar? Sarah Palin campaigned in that very place in 2008."

9:46 a.m. ET: Ryan finished his speech, saying "I'm excited for what lies ahead and I'm thrilled to be a part of America's Comeback Team. And together, we will unite America and get this done."
Romney's usual campaign song, Kid Rock's "Born Free," began blasting as the crowd cheered.
The two candidates' families joined them on stage.
9:44 a.m. ET: Ryan is finishing up his speech by listing his perceived contrasts between the GOP ticket and the Democrats: "We won't duck the tough issues, we will lead! We won't blame others, we will take responsibility! We won't replace our founding principles, we will reapply them!"
9:42 a.m. ET: Ryan: "We Americans look at one another's success with pride, not resentment, because we know, as more Americans work hard, take risks, and succeed, more people will prosper, our communities will benefit, and individual lives will be improved and uplifted."
9:39 a.m. ET: Ryan, to cheers: "I'm proud to stand with a man who understands what it takes to foster job creation in the economy. That knows if you have a small business, you did build that."
That's a reference to a speech Obama gave in July. Here's the full quote from Obama:
"If you are successful, somebody along the line gave you some help. There was a great teacher somewhere in your life. Somebody helped to create this unbelievable American system that we have that allowed you to thrive. Somebody invested in roads and bridges. If you've got a business, you didn't build that. Somebody else made that happen. The Internet didn't get invented on its own. Government research created the Internet so that all the companies could make money off the Internet."
9:37 a.m. ET: Former Minnesota Gov. Tim Pawlenty, previously considered a top VP pick for Romney, released the following statement Saturday:
"Congressman Ryan is a respected leader and a bold thinker regarding the changes needed to restore America. His selection will also help Governor Romney win the key swing state of Wisconsin. I am excited about a Romney-Ryan ticket and look forward to doing all I can to help them win this election."
9:35 a.m. ET:
9:34 a.m. ET: Ryan: "My dad died when I was young. He was a good and decent man. He said you’re either part of the problem or part of the solution. Pres Obama has become part of the problem, not the solution."
9:32 a.m. ET: Ryan: I am committed in heart and mind to putting my experience to work in a Romney administration.
9:31 a.m. ET:
9:30 a.m. ET: Ryan, wearing a dark jacket over a white shirt with no tie, says "Gov. Romney is the man for this moment."
9:29 a.m. ET: Romney corrected his mistake: "I'm known to make a mistake every once and a while. I didn't make a mistake with this guy."
9:28 a.m. ET: Romney introduced Ryan as "The next president of the United States." (Yes he said "president" not "vice president") Ryan walked on stage to the same music as Romney.
9:27 a.m. ET: Romney: "Today's a good day for America, and there are better days ahead"
9:25 a.m. ET: President Barack Obama's campaign manager Jim Messina released the following statement as Romney was speaking Saturday, reacting to Romney's choice of Ryan as his running mate.
“In naming Congressman Paul Ryan, Mitt Romney has chosen a leader of the House Republicans who shares his commitment to the flawed theory that new budget-busting tax cuts for the wealthy, while placing greater burdens on the middle class and seniors, will somehow deliver a stronger economy. The architect of the radical Republican House budget, Ryan, like Romney, proposed an additional $250,000 tax cut for millionaires, and deep cuts in education from Head Start to college aid. His plan also would end Medicare as we know it by turning it into a voucher system, shifting thousands of dollars in health care costs to seniors. As a member of Congress, Ryan rubber-stamped the reckless Bush economic policies that exploded our deficit and crashed our economy. Now the Romney-Ryan ticket would take us back by repeating the same, catastrophic mistakes.”

"Jane and I wish Paul and Janna and their kids the very best. As the Chairman of the Romney campaign in Ohio, I look forward to working with Paul to ensure that the Romney-Ryan ticket carries Ohio and is victorious in November.
