The Washington Post reports:
Two officials at the White House Office of Management and Budget recently resigned in part over concerns about the holdup on Ukraine aid, a career employee of the agency told impeachment investigators, according to a transcript of his testimony released Tuesday. Mark Sandy, the only OMB official to testify in the impeachment inquiry, did not name the employees in question.
He said one worked in the OMB legal division and described that person as having a “dissenting opinion” about how the security assistance to Ukraine could be held up in light of the Impoundment Control Act, which limits the ability of the executive branch to change spending decisions made by Congress. Sandy, the agency’s deputy associate director for national security programs, testified on Nov. 16, and his remarks revealed some of the White House’s internal maneuverings relating to blocking the aid.
