(William "Bill" Barr + Robert Mueller + Saudi Arabia) = "9/11 has not been properly investigated"?

"Months after President Donald Trump promised to open FBI files to help families of the 9/11 victims in a civil lawsuit against the Saudi government, the Justice Department has doubled down on its claim that the information is a state secret.

In a series of filings just before a midnight court deadline on Monday, the attorney general, William Barr; the acting director of national intelligence, Richard Grenell; and other senior officials insisted to a federal judge in the civil case that further disclosures about Saudi connections to the 9/11 plot would imperil national security."

"After a lengthy investigation, special counsel Robert Mueller charged Russia made “multiple, systematic efforts to interfere in our election” and said the incursion “deserves the attention of every American.”

But former FBI investigators say their old boss didn’t feel the same concern when they uncovered multiple, systemic efforts by the Saudi government to assist the hijackers in the lead-up to the 9/11 attacks — a far more consequential, to say nothing of deadly, foreign influence operation on America."

"Trump believes that 9/11 has not been properly investigated and he plans to get to the bottom of it. “First of all, the original 9/11 investigation is a total mess and has to be reopened,” Trump said."
