The lack of fairness in the impeachment of President Donald Trump is once again evident after Democrats used a Government Accountability Office (GAO) opinion to justify the impeachment process.

According to The Hill, the GAO accused the White House Budget Office of violating the law by withholding military aid to Ukraine, one of the main issues amid the Trump indictment. However, in 2014, during the Obama administration, the GAO discovered a violation of federal law, although by then it did not go beyond a call for a trial.

As reported by The Gateway Pundit, the GAO ruled in 2014 “that Obama’s prisoner swap of five detainees at Guantanamo Bay prison in exchange for deserter Bowe Bergdahl violated federal law.”

“The Department of Defense violated section 8111 of the Department of Defense Appropriations Act, 2014 when it transferred five individuals detained at Guantanamo Bay, Cuba, to the nation of Qatar without providing at least 30-days notice to certain congressional committees,” the government agency said at the time.

Meanwhile, from the Budget Office, spokeswoman Rachell Semmel said she did not agree with the recent GAO report.

“The OMB uses its apportionment authority to ensure taxpayer dollars are properly spent consistent with the president’s priorities and with the law,” Semmel said.

Also, a senior Trump administration official said they believed the GAO was trying to insert itself into the impeachment at a time when it is receiving high media attention, Fox News reported.

“The GAO has a history of the flip-flops, reversing 40-years of precedent this year on their pocket rescission decision, they were also forced to reverse a legally faulty opinion when they opposed the reimbursement of federal employee travel costs,” the senior official said.

“In their rush to insert themselves into the impeachment narrative, maybe they’ll have to reverse their opinion again and again,” he added.

As The Hill noted, at a press conference Thursday on Capitol Hill, House Speaker Nancy Pelosi (D-Calif.) said, “Every day new incriminating evidence comes forward. (…) I think that only speaks very clearly to the need for the Senate to enter the documentation into their discussion.”

Senate Minority Leader Chuck Schumer (D-N.Y.) endorsed the GAO report while demanding that the Senate allow the inclusion of additional documents as evidence in the upcoming impeachment.

The announcement of the report was made just before the Senate accepted the two articles of impeachment from House Democrats.

The House passed the resolutions on Dec. 18 accusing Trump of abusing his power to gain political favors from Ukraine and then allegedly obstructing Congress while the Democrats investigated the matter, The Hill reported.

According to Fox News, the Trump administration’s Budget Office is accused of withholding a total of approximately $400 million in security aid to Ukraine.

The move comes after President Trump met with Ukrainian President Volodymyr Zelenskiy to discuss the possibility of investigating this year’s Democratic candidate, Joe Biden, given allegations that he and his son Hunter Biden were in a fraudulent business deal with the renowned Ukrainian gas and energy company Burisma.

Such actions led to an impeachment trial against Trump from the Democratic-majority House, which resumes with new hearings this time in the Senate and will begin next week.
