PRESIDENT OBAMA: ABC News' Arlette Saenz: " President Obama Wants to Be 'Pioneer of Insourcing'" President Obama said he wants to be a "pioneer of insourcing," in contrast to his opponent, Mitt Romney, who Obama and his campaign are attempting to characterize as a "pioneer of outsourcing." "I believe in making things here in America and I believe in inventing things here in America, and Governor Romney his main calling card for running for office is his business experience, and so understandably American people have been asking 'Well, let's find out what you've been doing,'" Obama said to a crowd packed into the Austin Music Hall.

ABC News' Devon Dwyer: " Obama Campaign Sues to Extend Ohio Early Voting" President Obama's re-election campaign has filed suit in federal court to block a Republican-sponsored Ohio law that mandates an end to early, in-person voting a full three days before Election Day this fall. The lawsuit is the latest twist in an ongoing battle over early voting in the state between Obama allies and the Republican-controlled Ohio legislature and Gov. John Kasich. LINK

MITT ROMNEY: The New York Daily News' Thomas Defrank: " Medal-winner in Mitt Romney veep stakes won't be known until after Olympic Games" Kicking the vice presidential sweepstakes into overdrive, Mitt Romney Tuesday announced his running mate's staff - but is still debating when to unveil his actual choice for No. 2 on the GOP ticket. Sources close to the Romney campaign told the Daily News the working plan has been to announce the pick after the Olympic Games, which begin next week and conclude Aug. 12 - two weeks before the Republican convention in Tampa.

The Washington Times' David Sherfinski: " Romney team gets outgunner on rapid response to Obama" Even as Mitt Romney was readying one of his strongest direct attacks yet on President Obama on Tuesday in Pennsylvania, Mr. Obama's campaign pre-empted him with its own attack ad in the state, a turn of events emblematic of the Republican challenger's struggle to impose his own narrative to drive - and win - what is now a 24-hour news cycle. LINK

The Hill's Alexander Bolton: " GOP prods Romney on tax returns" Several Republican lawmakers prodded Mitt Romney to release additional tax returns and other financial documents in order to shift the presidential campaign debate back to the economy. Romney has been on the defensive for the past few weeks as President Obama and his reelection team have successfully hammered him on the issue of his wealth and his lack of disclosure about it. LINK

The Los Angeles Times' Seema Mehta: " Romney campaign's attacks on Obama play on 'birther' fears" In remarks that played on debunked assertions about President Obama's birthplace, Mitt Romney on Tuesday said that the current administration resembled foreign governments and one of his chief surrogates said the president needed to "learn how to be an American." The remarks - former New Hampshire Gov. John H. Sununu later apologized for the latter comment - came as Romney tried to change the subject from calls for his tax returns and questions about the length of his tenure at the venture firm Bain Capital. Both issues have fueled sustained attacks from Democrats and even some Romney allies. LINK

USA Today's Fredreka Schouten: " Supplement industry boosts Romney campaign by $4.5M" Executives with companies selling everything from energy drinks to weight-loss pills made from African mango-seed extracts are among the ranks of Republican Mitt Romney's top fundraisers, a USA TODAY analysis shows. Overall, individuals and companies with ties to the nutritional and dietary supplement industry have poured more than $4.5 million into campaign accounts benefiting Romney's presidential ambitions, federal records show. LINK

The Wall Street Journal's Colleen McCain Nelson and Sara Murray: " Romney's Ticket Talk Is Heating Up" In the time before his party's national convention late next month, Mitt Romney still has one surefire way to draw the spotlight to his campaign: When he names a running mate, the choice will dominate the political conversation. But both the person he selects and the timing of the announcement come with trade-offs that the Romney camp must weigh. LINK

Bloomberg's Julie Hirschfeld Davis: " Romney Resisting More Tax Disclosures Hits Obama on Jobs" Romney Resisting More Tax Mitt Romney, facing heightened attacks by President Barack Obama's campaign for refusing to disclose more of his tax returns, confronts escalating calls from within his own party to put the issue to rest by providing additional filings. LINK

The New York Times' Ashley Parker and Michael Barbaro: " Caution, Not Flash, as Romney Seeks His No. 2" Aides to Mitt Romney have pored over video footage of potential running mates, studying hundreds of hours of Sunday news show appearances, campaign debates and stump speeches for insight into how they handle unwelcome inquiries, even hecklers. They have instructed possible No. 2's to fill out a questionnaire with about 80 detailed and sometimes intrusive questions covering the financial and the personal, including, "Have you ever been unfaithful?" LINK

OTHER: The Boston Globe's Matt Viser: " Romney, Obama mine funds overseas" Mitt Romney and President Obama are stepping up efforts to get campaign donations from Americans living half a world away, a new twist in a rapidly shifting and intensely competitive campaign finance environment. Romney has reportedly sent two of his sons to Hong Kong to raise money, and is planning another round of fund-raising in London while he is there for the Olympics. Obama's surrogates held a fund-raiser at a Shanghai hotel last Wednesday and next month will dispatch actor George Clooney to Geneva to collect donations. LINK
