President Bush (search) went to Capitol Hill Thursday to thank House and Senate Republicans for narrowing their differences over this year's tax bill.

Bush once called a $350 billion tax-cutting plan "itty bitty." Is the president satisfied with Congress’ compromise? We’ll ask Speaker of the House Dennis Hastert.

And, will half the plan only do about half the job of lifting this saggy economy? We’ll ask William Beach, director of data analysis at the Heritage Foundation.

Plus, how will the markets react to the president’s tax cut? Mary Farrell, managing director and senior investment strategist at UBS Paine Webber, and Knight Kiplinger, editor of Kiplinger's Personal Finance, join the debate.

We’ll ask Sen. John McCain, R-Ariz., if enough is being done to protect the homeland this holiday weekend.

And, Warren Buffett, George Soros, Alan Greenspan -- some of the biggest names in business are giving the president’s economic policy a big thumbs down. Should we listen to these guys? We'll debate the issue with Forbes magazine's Bob Lenzner.

Plus, where’s the beef? Following a mad cow scare, are Canadian beef exports are serious trouble? Ben Thorlakson, chairman of the Canada Beef Export Federation.
