The war in Iraq has seen a recent flare-up of violence as General Petraeus prepares to testify before Congress early next month. What is the current situation in Iraq? Has the surge been a continued success and has the Iraqi government been able to increase their presence? We'll ask two influential senators, Republican Lindsey Graham and Democrat Jack Reed, only on "FOX News Sunday."

Plus, the race for the Democratic presidential nomination continues to heat up between the Clinton and Obama campaigns. As the battle turns to the Pennsylvania primary, is the infighting among Democrats hurting their chances in the general election? We'll sit down with key strategists from both sides.

Then, does the fight within the party over the role of superdelegates threaten to split the Democrats? Joining us will be Brit Hume, Washington managing editor of FOX News; Jill Zuckman of the Chicago Tribune; Bill Kristol of the Weekly Standard, and Juan Williams of National Public Radio.

Plus, our Power Player of the Week brings the nation’s pastime to the nation’s capital. We’ll sit down with Washington Nationals Team President Stan Kasten, as he gets ready to open Washington's new ballpark.

So check your local listings and we'll see you on the next "FOX News Sunday."
