They mean the same thing. I'm not having this argument again. The facts are:
(1) The Trump Admistration placed a freeze on Congressionally authorized military aid to the Ukraine in the middle of July.
(2) The whistleblower's complaint was filed on August 12th.
(3) President Zelensky was scheduled to appear on CNN for an interview with Fareed Zakaria on September 5th to, presumably, announce an investigation into the Bidens.
(4) This was canceled once the House Oversight Committee became aware of the whistleblower's complaint on September 3rd and demanded that it be forwarded to them.
(5) At first, the White House refused to forward the whistleblower's complaint to Congress as required by law. After Mitch McConnell declined to come to their defense over their refusal to forward the complaint to Congress,
(6) the White House then lifted the freeze on military aid on September 9th and
(7) then forwarded the whistleblower complaint to the House Oversight Committee on September 16th.
The chronology is very clear on this matter: The Trump Administration did not release the hold on the military aid to the Ukraine until
AFTER they became aware of the content of the whistleblower complaint and therefore, had no choice but to do so. They knew what was coming.... and every indication we have, is that President Zelensky would have complied with Trump's demand of announcing an investigation into the Bidens on CNN on September 5th - but the whistleblower complaint changed everything.
