President Barack Obama said the reason he told Russia’s Dimitry Medvedev back in March–more than seven months before this year’s presidential election–that he would have “more flexibility” after the election to work with Russian leader Vladimir Putin was because he was too busy campaigning and doing other “stuff.”

“The discussion there very much just had to do with the fact that it’s hard to negotiate additional treaties when I’m off campaigning and doing all kinds of stuff,” Obama said on Friday, explaining his open-mic comments with then-Russian President Dmitry Medvedev earlier this year.

The president’s latest comments came during an interview with News 4 KRNV in Reno, Nevada in which the questions were sent in from audience members.
