Barack Obama

Calling talk among Republican senators of proceeding with a plan to repeal the estate tax "mind-boggling," Sen. Barak Obama, D-Ill., said the country could not fight a war in Iraq, rebuild the Gulf region and deal with other domestic needs while cutting taxes for the wealthy.

"We need some adult supervision of the budget process. And we need to take responsibility for this process. That's something that we need from the president as well as our congressional leaders," Obama told CBS' Face the Nation.
