INDIANOLA, Iowa (AP) — Vice President Joe Biden is playing down the Obama administration's pledge to use military force to rid Syria of chemical weapons while he's in Iowa.

Speaking to a decidedly anti-war audience today, Biden instead touted the U.S.-Russian diplomatic proposal for Syria to relinquish its chemical arsenal under international supervision.

The vice president told hundreds attending Sen. Tom Harkin's annual steak picnic and fall fundraiser, "We're going to the United Nations with a resolution this week that will in fact call on the United Nations of the world to put pressure on Syria to have the confiscation and destruction of all those weapons."

Biden touched only lightly on the administration's continued insistence that "there are consequences should the Assad regime not comply."

There was no applause for his Syria comments from the audience, supporters of Harkin, a veteran Democrat popular with his party's anti-war activists.

Biden is weighing a run for president in 2016.
