Katie Couric's Notebook: Busy Week

It's an historic week in an already historic year.

That's the way White House Chief of Staff Rahm Emanuel described the days ahead...as President Obama faces critical moments on some of the most crucial challenges of his administration.

The Senate will begin debate on the health care reform bill, a bold and sweeping initiative that some critics say could be his Waterloo. The Democrats need 60 votes, but battles over a public option and federal money for abortions will may make that number tough to reach.

Tomorrow night, it's all about Afghanistan. In a primetime address from West Point, the president is expected to announce plans for moving forward, including a troop increase.

And then later in the week, the discussion turns to jobs....and an unemployment rate hovering above 10 percent.

The President inherited a world of problems...this week will test his ability to convince impatient Americans his policies will lead to solutions and change they can still believe in.

That's a page from my notebook.
