Mark Sandy

Career Sandy is a career official with the U.S. federal government. He has served under both Republican and Democratic administrations. By 2019 he had become a senior career official at the Office of Management and Budget, senior enough so that he served as acting director early in the Trump administration, before political appointees were hired. In testifying during the impeachment inquiry, Sandy became the first OMB official to meet with investigators after higher ranking political appointees fought subpoenas and refused to provide requested documents.

Sandy was signatory on at least one "apportionment letter" that delayed the release of military aid to Ukraine in 2019. On November 16, 2019, he testified in a deposition that Trump did in fact enact an unusual freeze in aid to Ukraine.
