President Vladimir Putin's military mission in Syria is a sign of Russia's weakness, not a show of its leadership, says President Obama. Russia has been forced to prop up a teetering Assad regime, he maintains, Russia's only ally in the region. Mr. Obama speaks at length to Kroft about the situation in Syria and about domestic politics, including his opinions on Hillary Clinton's use of a private email server, whether his vice president, Joe Biden, will run for president, and his take on Republican presidential candidate Donald Trump. The interview will be broadcast on 60 Minutes Sunday, October 11 at 7:30 p.m ET/PT.

An excerpt from the 60 Minutes interview was broadcast on CBS This Morning. A transcript of that excerpt is below:

Steve Kroft: A year ago when we did this interview, there was some saber-rattling between the United States and Russia on the Ukrainian border. Now it's also going on in Syria. You said a year ago that the United States-- America leads. We're the indispensable nation. Mr. Putin seems to be challenging that leadership.
