A former Trump administration official, speaking on condition of anonymity to discuss intelligence matters, said Biden’s work on foreign affairs brought him into close proximity with the whistleblower either at the CIA or when he was detailed to the White House.
“This person, after working with Biden, may feel defensive towards him because he feels [Biden] is being falsely attacked. Maybe he is even talking to Biden’s staff,” the former official said. “Maybe it is innocent, maybe not.”
Last month, the whistleblower accused President Trump of abusing his position by asking Ukrainian President Volodymyr Zelensky to investigate Biden and his son, Hunter, who sat on the board of a Ukrainian gas company. His complaint is now at the center of a Democrat-led impeachment inquiry, prompting Trump and his allies to cry foul.
Biden was President Barack Obama’s “point man” on Ukraine, making a half dozen trips there in his eight years as vice president. Those trips involved briefings from senior intelligence officials and NSC officers, some of whom traveled with him to Kyiv and elsewhere.
