Ciaramella has worked for the Central Intelligence Agency for several years and was assigned to the White House during the end of the Obama administration. He worked closely with Biden in his role as an expert on Ukraine. Ciaramella also has ties to Sean Misko, a former NSC co-worker who now works for Representative Adam Schiff and the Intelligence Committee. According to The New York Times, the whistleblower first went to a CIA lawyer and then to an unnamed Schiff aide before filing the whistleblower complaint. The aide told the whistleblower to follow the formal process, but conveyed some of the information he learned from him to Schiff, without revealing his name, The Times reported.
The whistleblower’s ties to Democrats, including Biden, Schiff, former CIA Director John Brennan, former Director of Intelligence James Clapper and former National Security Adviser Susan Rice, have created controversy, with Trump and Republicans using his past work with them in an attempt to discredit him. Republican Rep. Louie Gohmert told a local radio station in his home state of Texas that many in Washington D.C. knew the whistleblower’s identity, calling him a “staunch Democrat,” and former “point person on Ukraine,” who never called out corruption in the Eastern European country.
