[EX Q]: That  in turn  led to attacks from fellow NBA star LeBron James against the commander-in-chief.
That policy did not stop  LeBron James  of the Cleveland Cavaliersfrom making it abundantly clear that they are unwilling to hear the president out  tweeting last week that the commander-in-chief is a âbumâ and noting that Curry told him that he did not intend to visit the White House anyway.
 James  also said  âGoing to the White House was a great honor until you showed up!â  referring to his meeting with former President Barack Obama.
U bum @StephenCurry30 already said he ain't going! So therefore ain't no invite. Going to White House was a great honor until you showed up! â LeBron James (@KingJames) September 23  2017
 James  voted for Hillary Clinton.
Obama invited  James  and then-President-elect Trump to the White House on the same day  November 10  2016.

[EX Q]: But once the data is downloaded  it has to be analyzed. And thatâs where  Booz  and the other contractors that surround the NSA come in.
 Booz Allen Hamilton  is one of the NSAâs most important and trusted contractors. Itâs involved in virtually every aspect of intelligence and surveillance  from advising top officials on how to integrate the 16 U.S. spy agencies to detailed analysis of signals intelligence  imagery and other critical collections technologies. I first introduced Boozâs intelligence business in a 2007 profile in Salon when President Bush appointed Michael McConnell  a Booz veteran and former NSA director  to be director of national intelligence ( he âs now back at  Booz ).
Among other secret projects   Booz  was deeply involved in âTotal Information Awareness â the controversial data-mining project run for the Bush administration by former National Security Adviser John Poindexter that was outlawed by Congress in 2003.
Another major presence at NSAâs Business Park is SAIC. Like  Booz   it stands like a private colossus across the whole intelligence industry. Of its 42 000 employees  more than 20 000 hold U.S. government security clearances  making it one of the largest private intelligence services in the world. âSAIC provides a full suite of intelligence  surveillance and reconnaissance (ISR) and cybersecurity solutions across a broad spectrum of national security programs â it claims on its website.
