Nunes’s letter also lists State Department officials in Washington, who have admitted to receiving information from ex-British spy Christopher Steele, who was hired by Fusion GPS to dig up ties between then-candidate Donald Trump and Russia for the Clinton campaign and the Democratic National Committee.
Nunes’s letter also lists Colin Kahl, former national security adviser to former Vice President Joe Biden, another former Biden aide, and former journalist Shailagh Murray – who is married to a Fusion GPS executive Neil King, Jr. – as well as former top Clinton State Department aide and campaign official Jake Sullivan.

"Hillary Clinton's top national security and foreign policy staffer Jake Sullivan was one of the authors of messages that appeared on several Hillary Clinton email chains recently labeled "top secret" by the State Department, according to multiple intelligence sources who have seen the correspondence.
Sullivan, then deputy chief of staff to the secretary of state, is now senior policy adviser to the 2016 Democratic front-runner. Sullivan’s lawyer Beth Wilkinson did not respond to a request for comment.
Sullivan both initiated email conversations and also forwarded along messages with sensitive information, and he sometimes added additional content on the email chains in question, according to the sources. Those chains are now maintained at the highest classification level for national security information, though the campaign has long maintained they were not marked classified at the time they were sent.
The news that Sullivan was among those sending sensitive information is in some ways unsurprising, given his position at the State Department and his closeness to Clinton. But if the emails show that he mishandled sensitive information, one of Clinton's closest aides could come in for further investigation and scrutiny by congressional investigators.
"A third source said that Sullivan was one of about three individuals who sent such content to Clinton. It is unclear who else was involved in the email discussions."
