SNEAK PEEK: 9/11 and Iraq hearings

September 10, 2007— -- Tuesday marks the sixth anniversary of the attacks of Sept. 11 and it will be quiet on the campaign trail as some candidates observe the day and some head to Washington for business in Congress.

The candidate most identified with the day, Rudy Giuliani, will attend the sixth anniversary remembrance of the World Trade Center attack and read a passage at the ceremony.

(Though, the AP reports, he is not welcomed by everyone there. LINK)

In Washington, all eyes will once again be on Capitol Hill where Gen. David Petraeus and Amb Ryan Crocker will head over to the Senate side to testify before the Foreign Relations Committee at 9:30am ET and the Armed Services Committee at 2pm ET.

Today's testimony from Gen. Petraeus and Amb. Ryan Crocker was greeted with a full page ad in the New York Times reading "General Petraeus or General Betray Us?" (and protestors in the hearing room).

John McCain called the ad from the liberal anti-war group Moveon.org a "McCarthyite attack," Fred Thompson called upon Democrats to "repudiate the libel of this patriotic American" and Mitt Romney called it "deplorable tactics."

ABC's Jake Tapper reports that when asked if they would condemn the MoveOn.org ad, the Democratic presidential frontrunners (via their spokespeople) all demurred but tellingly, all of them refrained from criticizing Gen. Petraeus personally.

Tomorrow will be noteworthy not just because of the two men testifying but also the lineup of senators in the room.

Five presidential candidates will be a part of the two hearings tomorrow – Joe Biden chairs the Senate Foreign Relations Committee hearing at 9:30 am ET and is joined by Barack Obama, Chris Dodd. McCain and Hillary Clinton will attend the Senate Armed Service Committee at 2 pm ET. (It's a good thing for Sen. Clinton that the hearing takes place in Washington, DC and not Florida or she may upset Iowa political press corps dean David Yepsen two days in a row. LINK)

McCain will starts the day on Capitol Hill at 10 am ET for the Senate's 9/11 memorial event. After the Foreign Relations Committee hearing, he will fly to Sioux City, IA for a 7:30 pm ET kick-off to his "No Surrender Tour," an effort to rally support for the surge leading up to a debate in Congress about troop funding, ABC's Bret Hovell reports.

More from Hovell: McCain will be back on a bus along with some Veteran buddies, and they'll be dropping by VFW Post and American Legion halls across Iowa, New Hampshire and South Carolina. The "No Surrender Tour" is certainly about Iraq, but it's no accident that the name could apply to McCain's campaign as well. After a week that saw positive newspaper columns about his campaign in the New Hampshire Union Leader and the Washington Post, a strong debate performance in New Hampshire, and consistent energy on the stump, McCain's message of "No Surrender" means many things to many people… "We're glad to have you back" a McCain supporter told the Senator in California on Friday.

On the Republican side…Former Gov. Mitt Romney will attend wreath laying ceremony at Boston Public Gardens 9/11 Memorial at 8:30 am ET.

Fred Thompson is in Tennessee with no public events scheduled.

Sam Brownback is in Washington for Senate business.

Duncan Hunter will mark the anniversary in Washington by "working at his job to help make sure it does not happen again," according to his staff.

Rep. Tom Tancredo and other representatives will be in the Cannon building to hold a 12 pm ET briefing with members of the Iraqi and UK parliaments and European Union to discuss options for Iraq.

And the Democrats…ABC News' Donna Hunter reports that Chris Dodd joins the list of 2008 presidential hopefuls in the quest for book sales – his new book, "Letters from Nuremberg My Father's Narrative of a Quest for Justice," hits stores tomorrow/ The book is a compilation of letters Dodd's father Sen. Thomas J. Dodd wrote to his wife Grace while serving as the number two U.S. Prosecutor on the Nuremberg trials post World War II in the summer of 1945.

Hunter said that Dodd received a $30,000 advance for "Letters from Nuremberg," which is only a fraction of what his better known Presidential contenders received for their books. Obama's "The Audacity of Hope" fetched a $425,000 advance against royalties; John Edwards received a $500,000 advance for "Home: The Blueprints of Our Lives," and Biden received a $112,000 advance for "Promises to Keep: On Life and Politics," released last month.

John Edwards and his wife are in South Carolina. They have no public events scheduled for 9/11.

Gov. Richardson has no public events scheduled.

Dennis Kucinich is in Washington.

Mike Gravel will be in New York City for a press conference at City Hall at 1 pm ET and then heads to the United Nations at 2:30 pm ET to discuss the Petraeus report as well as make remarks on the anniversary of 9/11.
