GAY MARRIAGE – The battle over gay marriage moved to Federal Court in California today, where two gay men and two gay women are challenging the state’s ban on gay marriage, and are hoping to take the issue all the way to the U.S. Supreme Court. Our coverage of the issue begins with a report from San Francisco by our correspondent there Spencer Michels. After that, Ray Suarez interviews Margaret Talbot of “The New Yorker”. Her coverage of the gay marriage issue is prominently featured in the latest edition of the magazine.

CADILLAC PLANS: President Obama spent the afternoon meeting labor union leaders at the White House, and discussing health care reform among other issues. Tonight, Gwen Ifill looks at the pros and cons of the so-called “Cadillac Plan Tax” with Jonathon Gruber, a Health Economist at MIT and a paid consultant to the Obama Administration; and Josh Bivens, an Economist at the Econonic Policy Institute.

FRAGILE STATES: Special Correspondent Kira Kay continues our series of reports on some of the world’s “Fragile States”. Tonight she reports from Haiti, a nation struggling to overcome decades of political turmoil and poverty. Her report is produced in partnership with the Pulitzer Center on Crisis Reporting.

SUPREME COURT: The Supreme Court today started reconsidering an issue that it looked at as recently as 7 months ago. Then, in a 5-4 ruling, the Court argued that crime laboratory results cannot be used in a trial unless the analyst who prepared them testifies and is available for cross-examination. Today, with Justice Sonia Sotomayor now sitting on the Court, the issue came up again. Margaret Warner talks to Marcia Coyle of the National Law Journal about whether the new configuration of the Court might lead to a new judicial interpretation.

NBC’S TRAVAILS: Finally, Jeffrey Brown examines the problems facing the NBC television network, as it shuffles its late-night lineup and moves Jay Leno out of prime time. Jeff’s guests will be Robert Thompson of Syracuse University, and Kim Masters of KCRW Public Radio in Los Angeles.

WEB-ONLY – Finally, Hari Sreenivasan gives a tour of the newest features on our website including: an interview with Tom Rosenstiel of the Project for Excellence in Journalism about a new study showing most original reporting in this age of “new media” comes from “old media,” especially newspapers; more about which health insurance policies qualify as the so-called “Cadillac” plans that would be taxed under the Senate proposal; a quick take from four foreign policy experts on President Obama’s first year in office; and an Art Beat interview with music critic Terry Teachout about his new biography on jazz legend Louis Armstrong.

All that, plus the other news of the day. Gwen Ifill and Jeffrey Brown anchor Monday’s PBS NewsHour, and we hope that you’ll join us.
