It's not a well-written PR by normal writing standards.
They have problems introducing guests. It should just be "Former CIA director George Tenet" instead of ponderous and confusing "The former CIA Director under presidents Clinton and Bush..." without even mentioning his name!
Also, it's unclear what's going on. Is he speaking October 20th or October 21rst? Is the opening the 20th or the 21rst?
How can you open a meeting on the 20th if it's to be held on the 21st?
