About a year ago, presidential candidate Barack Obama was having breakfast at Glider's Diner in Scranton, Pennsylvania before another long day of campaigning.

It was during this breakfast that a reporter kept hounding Obama for his reaction to President Jimmy Carter's "positive" meeting with Hamas. Obama, who was obviously hungry at the time, responded by asking a question of his own.

"Why can't I just eat my waffle?" Obama asked.

Fast forward a year and Obama is now getting all the "waffles" he can handle.

What's the latest steaming stack giving his nascent administration heartburn? It's Democratic House Speaker Nancy Pelosi's ongoing two-step on what she knew and when regarding the Central Intelligence Agency's (CIA) use of enhanced interrogation techniques.

According to the Washington Post, "Pelosi for several weeks has insisted she was never briefed on the use of waterboarding. She did not point out that in December 2007 she issued a little-noticed statement that said she became aware of waterboarding in February 2003…"

Further, the newspaper reports, "…The CIA released a detailed memo last Thursday outlining 40 congressional briefings given since September 2002…That memo included footnotes that appeared to contradict Pelosi's previous statements that she was never personally briefed…"

Rather than admit she suffers from a faulty memory, Pelosi and other Democrats are now calling for a "truth commission" to investigate who authorized the use of enhanced interrogation techniques.

That's right. Pelosi wants to waste taxpayer dollars investigating an issue she was briefed on more than six years ago.

For his part, President Obama has dismissed the idea of establishing such a commission. Much to his credit, the president recognizes establishing any sort of commission is a colossal waste of time and money.

President Obama is also smart enough to recognize that every day Pelosi waffles on this issue – pointing fingers and refusing to admit what she knew and when – is another day she is single-handedly derailing his agenda.

That's why it's only a matter of time before the president dispenses some hearty advice to Pelosi.

"Shut up and eat your waffle, Nancy."
