Sunday: Collins, Gardner and Schiff

NEW YORK, NY - SEPTEMBER 19: President Donald Trump speaks to world leaders at the 72nd United Nations (UN) General Assembly at UN headquarters in New York on September 19, 2017 in New York City. This is Trump's first appearance at the General Assembly where he addressed threats from Iran and North Korea among other global concerns.

Leaders from across the globe descended upon New York City this week for the United Nations General Assembly, where President Trump gave an incendiary speech covering United States' handling of global flashpoints like the recent provocations from North Korea and the Iranian nuclear agreement.

But as the eyes of the world were mostly fixed on Mr. Trump's debut at the U.N., Congress was in session, continuing the debate over what to do about health care. Hill Republicans spent countless hours fishing for the votes they needed to pass the buzzer-beater Graham-Cassidy bill, which many hoped to bring up for a vote next week before a key procedural deadline. Despite this effort, on Friday, Senator John McCain dealt a blow to such efforts, saying that he could not in good conscience vote for it. 

In other domestic news this week, additional details surfaced about Russia's lucrative dealings and meddling in the U.S. election. There were also new developments indicating where the special investigation into the matter, led by Robert Mueller, might be heading.

This Sunday, we'll hear from Sen. Susan Collins, R-Maine, on the Russia investigation, health care, and more. The last time when GOP members attempted to pass a "skinny" health care bill in July, Collins voted against it. Has she made a final decision on this latest bill? And what can she tell us about the latest news coming out of the Russia investigation.

We'll also talk with Sen. Cory Gardner, R-Col., who sits on the Foreign Relations committee, about the provocations from North Korea, Mr. Trump's approach to the Iranian nuclear agreement, and more. We'll also get Gardner's take on the latest developments in the fight over health care.

Rep. Adam Schiff, D-Calif., the top Democrat on the House Intelligence Committee, will also join the broadcast. We'll talk with him about the investigations into Russian meddling, including the congressional inquiries into Facebook's selling of hundreds of thousands of micro-targeted ads to Russian cyber clients, the FBI's wiretapping and rumored future indictments of former Trump campaign chairman Paul Manafort and Mueller's zeroing in on Mr. Trump's firing of former FBI Director Jim Comey.

Given the Republican Party's extreme difficulty in passing replacement legislation for Obamacare and health care's close connection to tax policy, we'll talk with White House Legislative Affairs Director, Marc Short, about Congress' future endeavors and how the administration is looking to spend any political influence left for Capitol Hill.  

We'll hear from New Yorker writer Atul Gawande, the author of "Being Mortal: Medicine and What Matters in the End." He'll give us a first look at his upcoming report on what recent health-care reform efforts haven't addressed, and the existing problems in the health-care system.

Finally, we'll have a pair of expert journalists on to break down the foreign and domestic news. Washington Post reporter David Nakamura and CBS News' own White House and Senior Foreign Affairs Correspondent Margaret Brennan will join the broadcast.
