Our exclusive guests this week:
• Terry McAuliffe, Clinton campaign chairman
• Rep. Chris Van Hollen, D-Md., chairman of the Democratic Congressional Campaign Committee
• Rep. Tom Cole, R-Okla., chairman of the National Republican Congressional Committee

With Senators Clinton and Obama splitting this week’s primary wins, Clinton is running out of states — and time — to catch up to Obama in total delegate count. What is Senator Clinton’s strategy for coming out on top as the Democratic nominee and does she stand a chance with the Democratic Rules and Bylaws Committee meeting next week? Only then will they decide whether or not to sit the Florida and Michigan delegates at the convention.

Also, how would an Obama-Clinton ticket look and would Clinton agree to be Obama’s vice presidential nominee? We’ll talk about this and much more with Terry McAuliffe, Clinton campaign chairman.

Then, House Republicans offer various reform plans to get the party back on track as they have already seen three House seats that they considered very safe move over to the Democratic side since March. In the meantime, Democrats are enjoying their special election victories and are trying to use that momentum to gain even more seats in the election this fall. What’s the strategy for Democrats and Republicans heading into November? We’ll ask the chairmen of the two Congressional Campaign Committees: Reps. Chris Van Hollen, D-Md., and Tom Cole, R-Okla., only on "FOX News Sunday."

Plus, we’ll look at the possible choices for the upcoming "veepstakes." Joining us will be Brit Hume, managing editor of FOX News; Nina Easton of Fortune Magazine; Bill Kristol of the Weekly Standard, and Juan Williams of National Public Radio.

And, in honor of Memorial Day we’ll sit down with the director of the “President’s Own” — the U.S. Marine Band — Col. Michael Colburn.

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