Senate Majority Whip Dick Durbin (D-Ill.) said Sunday that critics of this weekend's budget deal have to face up to the reality of the situation.

"I would say to the folks on the right, as well as my friends on the left, there is a budget reality facing both political parties," Durbin said on CNN's "State of the Union." "We need to dramatically reduce the deficit that we are facing."

But Durbin warned that his party would not let spending cuts go too far.

"What we're trying to do as Democrats is to make sure that we don't go too far, and so we fought to make sure that we protected early childhood education, Pell grants for kids from low-income families who want to go to college, medical research grants," Durbin said. "These are the things which were essential and at the end of the day we won the battle."
