This article is from Sept. 2011. In it, it says Bob Graham is upset this information wasn't reported to the 9/11 Commission. I did quick searches for "Abdulazzi al-Hiijjii" and "Senator Bob Graham" and pretty immediately found this from a year later:

Former U.S. Sen. Bob Graham: Reopen inquiry into 9/11 attacks
By Juan Ortega, The Sun Sentinel, Sept. 11, 2012

[.....]    Former U.S. Sen. Bob Graham, at left, spoke to an audience Tuesday night during "Unanswered Questions of 9/11: A Conversation With Bob Graham." It was a seminar presented at the Museum of Art Fort Lauderdale by Broward Bulldog, an independent nonprofit online newspaper, and Boardroom Communications Inc., a marketing and public relations firm. [.....]

"I think it's very important that this information about Sarasota and Delray Beach and other places where the hijackers would have benefited from a support network be made available," Graham said.

The event, titled "Unanswered Questions of 9/11: A Conversation With Bob Graham," was presented at the Museum of Art Fort Lauderdale by Broward Bulldog, an independent nonprofit online newspaper, and Boardroom Communications Inc., a marketing and public relations firm. [.....]

During the past year, Broward Bulldog has been reporting about how Congress and the 9/11 Commission were left unaware of an FBI inquiry that scrutinized ties between the 9/11 hijackers and the Saudi family in Sarasota, who reportedly left the country just before the attacks.

Broward Bulldog last week filed a lawsuit demanding the release of FBI records that allegedly link the Sarasota family to the terrorists. The FBI has replied it found no credible evidence connecting the family and the 9/11 hijackers, according to Broward Bulldog editor Dan Christensen. But the FBI has rebuffed specific requests by several newspapers to provide details in support of its assertion, Christensen said.

The lawsuit, which names the FBI and U.S. Department of Justice as defendants, is pending in federal court in Fort Lauderdale. [.....]

If you follow this link there Broward Bulldog last week filed a lawsuit (note:that means it took them a year from the story you posted to file the lawsuit,)

I admit I haven't read those, because I'm not all that interested, and they have a lot of legal mumbo jumbo I would have to spend of time translating and I get a headache when I have to do that. I look at it big picture and I honestly can't see much of anything much coming out of this piece of data that might alter the big narrative of history.

But if you chose to do so, I would say keep in mind this is the Obama administration fighting this FOIA, not the Bush administration.

And I couldn't easily find any more complaints from Senator Graham about all this. Seems to me if it were something of earth shaking potential that would change the whole narrative, he would have been screaming bloody murder a year ago. And seems to me it's more like he would just like to see this info. included in public addenda to the 9/11 Commission Report for reasons of comprehensiveness and historians.

Instead of  spending time looking at these FOIA case docs, I chose to do a quick re-perusal of  Chapter 7 of the 9/11 Report where the hijackers movements in the US before 9/11 are reported:

That's a summary of an awful lot of people being investigated for coming in contract with the hijackers and perhaps supporting them. One that jumped out at me that I probably didn't recognize the first time I read it was Imam "Anwar Aulaqi" (often spelled Anwar Awlaki or Anwar Al-Awlaki) being interrogated about meeting with Hazmi and/or Hanjour in San Diego and Virginia. We now know what the Obama administration feels (felt?) about him (reminder: an American citizen, not a Saudi.) I find that a way more interesting thing to pursue than the tale of a Saudi family near Sarasota that might easily have gotten a tip from Atta or Shehhi to skidaddle before 9/11.

But anyone really interested should be able to contact The Broward Bulldog and/or Bob Graham to get a wassup. It's not like they are persecuted whistleblowers who can't talk and there isn't an internet.
