truth-out's article doesn't say anything about Brock or Kline, and it doesn't suggest that the Saudis own anyone.

Rather, the article suggests that Clinton is supporting terrorism via Saudi Arabia:

What did the Saudis get for their largesse and access? WikiLeaks revealed a 2009 cable by then-Secretary of State Hillary Clinton saying:"More needs to be done since Saudi Arabia remains a critical financial support base for Al Qaeda, the Taliban, Lashkar e-Tayyiba and other terrorist groups." Instead of sanctioning the Saudis, Clinton did the opposite: She authorized enormous quantities of weapons to be sold to them.
