The Note: Tar Heel Tangle

— -- NOTABLES

--OBAMA, CLINTON TAKE TO THE TRAIL: Hillary Clinton will campaign with a familiar figure today as President Obama joins her on the trail. President Obama endorsed Clinton on June 9, but their initial joint campaign appearance was rescheduled in the wake of the Orlando nightclub attack. Now the pair will hit the trail together today in Charlotte, North Carolina. The duo will "discuss building on the progress we've made and their vision for an America that is stronger together," a campaign press release stated. Meanwhile, presumptive Republican nominee Donald Trump holds his own rally in the Tar Heel State accompanied by Sen. Bob Corker of Tennessee, one of the GOP candidate’s running mate prospects.

--BY THE NUMBERS: A recent ABC News/Washington Post poll reported that 56 percent of overall respondents approved of President Obama’s job performance. The approval rating for Obama goes up dramatically among Democrats -- to 88 percent, dips to 50 percent among independents, and plunges to 18 percent among Republicans.

--ANALYSIS -- ABC’s RICK KLEIN: In this year of outsiders, Hillary Clinton gets some help Tuesday from the ultimate insider. The calculation in employing President Obama is easy, particularly as the president’s approval rating seems to rise in reaction to the year of Donald Trump. But as Trump demonstrates just about daily, the easiest calls can have the least predictable consequences. The teamwork plays into a core Trump theme – one with particular resonance as the FBI investigation into Clinton’s email system winds down. The fix is in, Trump will argue, pointing to campaign trips aboard Air Force One and the ill-advised tarmac meeting between former President Bill Clinton and Attorney General Loretta Lynch as exhibits A and B. Having high-profile surrogates at the ready is a good problem to have – and a problem Trump very much does not have. But it can’t be forgotten that coziness comes with consequences in 2016.

LAST WEEKEND ON THE TRAIL with ABC’s VERONICA STRACQUALURSI

RISING STAR JULIAN CASTRO BEING VETTED AS A CLINTON RUNNING MATE. Housing and Urban Development Secretary Julian Castro is being vetted as a potential running mate for presumptive Democratic presidential nominee Hillary Clinton, according to a Democratic source familiar with the process. Castro, 41, would be the first Hispanic candidate on a presidential ticket, ABC's BENJAMIN SIEGEL notes. His selection could help Clinton energize Hispanic voters and sharpen her contrast with presumptive Republican presidential nominee Donald Trump, who has courted controversy with his anti-immigrant proposals and incendiary rhetoric. http://abcn.ws/29iHU9p

Mike Pence, who is reportedly under consideration for the job, according to a Republican source.

Joni Ernst. has more. http://abcn.ws/29tEVJI

SANDERS WAGES FIGHT FOR DEMOCRATS TO SHOW 'STRONG OPPOSITION' TO TRANS-PACIFIC TRADE DEAL. Bernie Sanders is calling out Hillary Clinton delegates on the Democratic Party's platform-drafting committee for failing to support certain amendments regarding the Trans-Pacific Partnership (TPP) trade deal. In an op-ed published Sunday in the Philadelphia Inquirer, Sanders highlights parts of the party platform document that he supports, including language about Citizens' United, an expansion of Social Security and Wall Street reform. But he goes on to say the document, which the full drafting committee will vote on again before the party's convention this month, needs to be "significantly improved," ABC's MICHAEL EDISON HAYDEN notes. http://abcn.ws/29o9mDE

IN CASE YOU MISSED IT

TRUMP: REPUBLICAN NATIONAL CONVENTION SPEAKING SLOTS ‘TOTALLY FILLED’. Trump tweeted over the weekend that speaking slots at the Republican National Convention were already “totally filled, with a long waiting list of those that want to speak.” Trump also indicated in his tweet that the names of those speakers would be released within days: “The speakers slots at the Republican Convention are totally filled, with a long waiting list of those that want to speak - Wednesday release.” At a speech in Colorado last Friday, Trump said that his children and wife would all be speaking at the four-day convention in Cleveland, Ohio, that kicks off July 18. “Ivanka, Tiffany, Don, Eric -- they are going to be speaking,” Trump said. “My wife is going to be speaking at the convention. We’re going to have a great time.” Previously, Trump has also suggested having a “winner’s night” at the convention that would likely include nonpolitical speakers such as famous sports figures. http://abcn.ws/29eOWJY
