Both intend to argue that their interactions with UAE officials were part of their jobs, and Barak’s lawyers have said the US State Department and Trump himself were aware of his contacts with Middle Eastern officials. Any testimony from Trump will come as the Republican businessman-turned-politician faces a series of legal issues, including a federal investigation into his handling of presidential records after he left office and a New York state trial in October of his family company for tax fraud. A lawyer and a spokesman for Trump did not immediately respond to requests for comment. Barak’s lawyers said in an Aug. 26 court filing that Trump and members of his administration “cannot be ruled out as potential witnesses.” Twelve jurors and four alternates are set to serve in the trial, which is expected to last about a month. Prosecutors believe UAE officials briefed Barrack on what to say in television interviews and what Trump should say in a 2016 energy policy speech, and directed him to promote the interests of ally Saudi Arabia of the UAE. read more Barak was indicted last year on charges of acting as a foreign agent, conspiracy, obstruction of justice and making false statements in an FBI interview.
