根据美国国会下属监察机构政府问责局认定,特朗普政府去年扣留向乌克兰提供国会批准的军事援助“违反了法律”。这一裁决认定,总统无权搁置国会批准的对外国政府的援助,白宫预算办公室违反了《国会预算与节流控制法》。而该法规定,白宫不能扣留国会拨款。美国政府问责局主要为国会提供审计、监督、评估和调查服务,是联邦政府最高的审计和监督机构。
GAO says Trump administration broke law by withholding Ukraine aid
The Government Accountability Office (GAO) issued a legal opinion on Thursday saying that President Trump's administration broke the law by withholding defense aid to Ukraine — the issue at the heart of the president's impeachment trial.
That money, $214 million which had been allocated to the Department of Defense for security assistance, was appropriated by Congress and therefore the administration did not have the right to hold it back just because it disagreed with its allocation, the opinion from the nonpartisan government watchdog said.
"Faithful execution of the law does not permit the President to substitute his own policy priorities for those that Congress has enacted into law," the opinion said. "[The Office of Management and Budget] OMB withheld funds for a policy reason ... not a programmatic delay. Therefore, we conclude that the OMB violated the ICA [Impoundment Control Act]."
