President Barack Obama says House Speaker John Boehner is the only thing standing in the way of reopening the federal government.
Obama spoke at a small business just outside of Washington on the third day of the shutdown. He said Boehner is preventing a vote on a funding bill because he doesn't want to anger "extremists" in his party.
The President is calling on Boehner to quickly hold a vote on a bill free of extra demands.
The President met with Boehner and other congressional leaders at the White House for more than an hour Wednesday, but no agreement was reached.
Obama says the longer the shutdown goes on, the worse the impact on the U.S. economy will be.
House Republicans say they'll try again on Thursday to propose a piecemeal approach to reopening the federal government.
Votes are on tap for restoring funds for veterans and paying members of the National Guard and Reserves.
But Democrats say they're only interested in completely reopening the government by passing an emergency spending bill.
Worries are increasing that the impasse that caused the partial government shutdown could go on for weeks and get tangled in the imminent debate over increasing the limit of the country's borrowing authority.
An outside political group supporting House Democrats is casting blame for the government shutdown on nine House Republicans in a series of television and online ads.
House Majority PAC is launching a six-figure broadcast television ad buy this week against Republican Reps. Steve Southerland of Florida, Joe Heck of Nevada and Dave Joyce of Ohio.
The ads accuse the Republicans of causing the federal government shutdown. The GOP seats are top priorities for Democrats in the 2014 midterm elections.
The group is also planning online ads against House Republicans representing districts in California, Colorado, Illinois, Pennsylvania, New York and Minnesota.
The TV ads will air in Tallahassee, Fla., Las Vegas, and Cleveland, part of a larger effort by both parties to gain leverage in the government shutdown.
