Early life and career

In 2017, Eisenberg was appointed Deputy Assistant to the President, National Security Council Legal Advisor, and Deputy Counsel to the President for National Security Affairs by former National Security Advisor Michael Flynn and part of the National Security Council.

Trump Tower wiretapping allegations
On March 29, 2017, The New York Times reported that Michael Ellis and Ezra Cohen were involved in the sharing of intelligence documents to Representative Devin Nunes, chair of the House Intelligence Committee. The following day, The Washington Post reported that Eisenberg was also involved. In April 2017, the Associated Press quoted a U.S. official as saying that although Cohen had access to those kinds of intelligence materials, he did not play a role in helping Nunes gain access to the documents. According to a U.S. official, Cohen was not involved in showing the material to Nunes, did not clear Nunes onto the White House grounds, did not review the material with Nunes, and was not even aware that the material was going to be shared with Nunes.

Trump–Ukraine scandal
Eisenberg ordered a transcript of a Trump call with Ukraine's president be moved to a highly classified server and played a role in the Justice Department's early handling of the Trump–Ukraine scandal. The whistleblower initially submitted concerns anonymously to Courtney Elwood, general counsel of the CIA. Elwood then contacted Justice Department officials and Eisenberg. Eisenberg was notified by both Fiona Hill and Alexander Vindman that they were concerned about inappropriate comments to Ukrainian officials by European Union Ambassador Gordon Sondland and President Donald Trump.

Per Vindman's testimony, Eisenberg instructed Vindman not to tell anyone about the Trump call to President Volodymyr Zelensky. In early November 2019, Eisenberg was subpoenaed to testify by the House Intelligence Committee but refused.
