Interesting article but decidedly anti-Trump even though in the body of this story, a lot of the problems occurred and we not solved during the almost 8 years of the Obama regime.
Just look at the dates for a timeline from 2008 (election Nov. 2008, inauguration Jan. 20, 2009, so you have to give the new administration about 6-9 months to get settled in and projects up and running. However, the Democrats never gave Pres. Bush is leeway re 9/11. All the preparations for the attack took place before he was president and then when he had only been in office for less than 8 months, plus the FBI middle-management that existed under Clinton poo-poohed field agent reports on possible aircraft attacks on America.
You can slant anything anyway you want to, and leftist groups like ProPublica are experts at it.
Plus the fact that the CIA and FBI were not allowed to share info at that time.
