President Barack Obama was interrupted by a heckler Friday night who demanded of the president: “Tell us about your plans for nuclear war with Russia!”  
Mr. Obama was giving a speech to a meeting of the Democratic National Committee on Friday night at the Capital Hilton. The DNC speech came directly after Mr. Obama gave brief remarks to the nation in which he warned Russia not to use its military to intervene in Ukraine.
Here is a video of the exchange, and a transcript  provided by the White House: 
THE PRESIDENT: …And the fact is we’ve got a fundamental disagreement with the other side.  And that’s okay — this is a democracy, that’s how it works.  But we have a fundamental disagreement about what we need to do now to secure our future.  And don’t get me wrong, I consider –
AUDIENCE MEMBER:  Mr. Obama!
THE PRESIDENT:  — I consider Republicans patriots who love this country just as much as we do.
AUDIENCE MEMBER:  Tell us about your plans for nuclear war with Russia!
THE PRESIDENT:  I’m sorry, who’s that back there?  (Laughter.)  What the heck are you talking about?  (Applause.)
AUDIENCE:  Obama!  Obama!  Obama!
THE PRESIDENT:  No, no, don’t worry about it.  We’re okay.  Have a seat.  I don’t know anything about that plan.  (Laughter.)  I don’t know what you’ve been reading.  (Laughter.) Let me return to what I was talking about.  (Applause.)  See, he thought happy hour started earlier.  (Laughter and applause.)
Now, don’t get me wrong, I think the Republicans are patriots; they love this country just like we do.  They love their kids, they love their communities, but they just keep on offering a theory of the economy that time and again has failed America.  They think we should give more tax breaks to those at the top, and invest less in things like education and research.  I’m not making that up.  Go on their website.  That’s what they think.  They think we should let big banks and credit card companies and insurers do only what’s best for their bottom line without responsibility to their customers or their communities.
