CONGRESS ABC News' John R. Parkinson: "Rep. John Dingell to Break Record: 57 Years in Congress" Rep. John Dingell, who is serving his 30th term in the House of Representatives, is poised to break the record next week as the longest-serving member in the history of the U.S. Congress. Next Friday, June 7, Dingell will eclipse the late Sen. Robert Byrd, having served 57 years, 177 days. That's 20,996 days, to be exact. LINK

The New York Times' Jonathan Weisman: " In Congress, Legislation and Scandals Vie for Attention" Lawmakers will return to the Capitol on Monday from a weeklong recess, facing a critical juncture on immigration legislation and controversies at the Internal Revenue Service and the Justice Department that will test Congress's ability to balance its twin responsibilities of legislating and investigating. For President Obama, how those competing priorities balance out could mean the difference between securing a landmark accomplishment - the first overhaul of the nation's immigration laws since 1986 - or becoming consumed by charges of scandal.

The Washington Post's David Fahrenthold: " 'Temporary' farm subsidy program may finally meet the reaper" The building is one of the finest on Central Park West. Celebrity residents. Park views. Units priced at up to $24 million. It is most definitely not a farm. But last year, the U.S. government sent $9,070 in farm subsidies to an apartment here. Even the woman who got that money isn't exactly sure why. "I really don't know," Lisa Sippel said. Sippel does own farmland, but it's in Missouri. Somebody there does the work. LINK

Politico's Katie Glueck: " Report details how GOP lost young voters" A new postmortem on the November elections from the nation's leading voice for college Republicans offers a searing indictment of the GOP "brand" and the major challenges the party faces in wooing young voters, according to a copy given exclusively to POLITICO. The College Republican National Committee on Monday will make public a detailed report - the result of extensive polling and focus groups - dissecting what went wrong for Republicans with young voters in the 2012 elections and how the party can improve its showing with that key demographic in the future.

The Wall Street Journal's Peter Nicholas, Janet Hook and Damian Paletta: " Deficit Deal Even Less Likely" Shrinking near-term federal deficits, slowing health-care cost increases and partisan gridlock have all but wiped out the likelihood for a deal this year to reduce long-term U.S. deficits, perhaps delaying a compromise until after the 2014 midterm elections, White House officials and congressional lawmakers said.

USA Today's Erin Kelly: "Immigration bill faces tough path in full Senate" As the Senate heads back into session Monday, it is poised to take up a sweeping immigration bill that would offer earned citizenship to many of the 11 million immigrants who entered the United States illegally before 2012. Supporters of the bill crafted by the bipartisan "Gang of Eight" senators guided it to passage in the Senate Judiciary Committee last month while fending off amendments that would have broken apart their coalition of labor and business groups, Catholics and evangelical Christians, and law enforcement and civil rights' groups.

IRS The Hill's Meghashyam Mali: " Report: Treasury finds IRS spent $50M on conferences in 3 years" A review by the Treasury Department's inspector general found that the Internal Revenue Service (IRS) spent $50 million dollars on conferences for employees between 2010 to 2012, according to reports. The audit, set to be released on Tuesday, says the agency spent the funds on more than 200 employee conferences, including an August 2010 meeting in Anaheim, Calif., which cost taxpayers $4 million.

The Wall Street Journal's Andrew Ackerman and Michael M. Phillips: " IRS Faulted on Conference Spending" The Internal Revenue Service is facing criticism over past spending at its staff conferences, the latest controversy to hit the agency. An internal watchdog at the Treasury Department is set to report Tuesday that the IRS spent almost $50 million on more than 200 employee conferences from 2010 through 2012, spending the tax-collecting agency's new acting commissioner called "inappropriate."

GOV CHRISTIE ABC News' Shushannah Walshe: " Christie Pounds the Airwaves Against Opponent, Despite Huge Lead in Gubernatorial Campaign" New Jersey Gov. Chris Christie is leading his gubernatorial opponent,state Sen. Barbara Buono, by more than 30 points, but that hasn't stopped him from bombarding the airwaves with ads, including negative ones attacking Buono, and spending almost $4.5 million, according to the Christie campaign. It's easy to wonder why. LINK

HILARY CLINTON ABC News' Benjamin Bell: "David Plouffe: Hillary Clinton Is the Democratic Frontrunner if She Runs for President in 2016? Bloomberg TV contributor David Plouffe, who ran President Obama's 2008 campaign for president, said during an exclusive to web interview with "This Week," that former Secretary of State Hillary Clinton would be the Democratic frontrunner if she chooses to run for the White House in 2016, but added that others, including Vice President Joe Biden will look at potentially running for the presidency.

SEXUAL ASSAULT USA Today's Tom Vanden Brook: "Military chiefs to face tough sexual assault questions" Military service chiefs who will testify Tuesday about their plans to deal with the burgeoning crisis of sexual assault in the ranks will face a group of female senators determined to change a culture they call demeaning to women. Sen. Kirsten Gillibrand, who has proposed one of the most sweeping overhauls to the military justice system to deal with sex assault, made clear that only action, not pronouncements, will be acceptable.

SUPREME COURT The Wall Street Journal's Peter Landers:" Once Again, High Court Leaves Big Cases for Last" "Entering the final month of its 2012-13 term, the Supreme Court is following its custom of leaving its biggest decisions for the end. The court traditionally puts off its blockbusters until the last possible day, as exemplified by its rulings on gun control in 2010, violent videogames in 2011 and President Barack Obama's Affordable Care Act in 2012.

ATTORNEY GENERAL ERIC HOLDER The Boston Globe's Peter Baker and Charlie Savage: " Eric Holder weathers uproar amid speculation on future" At the end of last year, with the election decided and the Obama administration in office for four more years, Attorney General Eric H. Holder Jr. considered stepping down. He decided against it, in part because before he left he wanted to move beyond the disputes that had marked his tenure, accomplish some of the goals he had set for the job, and leave on his own terms.
