Obama defends campaign, jabs Republicans

WASHINGTON, Aug. 20 (Xinhua) -- U.S. President Barack Obama on Monday defended his campaign, denying accusations that he is running a negative reelection campaign, while jabbing the Republicans.

In an impromptu news conference at the White House, Obama said he felt "very comfortable with the fact that when you look at the campaign we're running, we are focused on the issues and the differences that are important to working families all across America."

The Republicans have been accusing Obama of running a negative campaign, focused on attacking his Republican challenger Mitt Romney, especially on Romney's tenure at the private equity firm Bain Capital and his reluctance to release tax returns, than talking about issues important to the American people.

Obama said he and Romney have different visions on how to fix the economy, Medicare, taxes, energy and education, adding "that's what I talk about on the campaign."
