The acting U.S. ambassador to Ukraine, Bill Taylor, reportedly told congressional investigators yesterday that President Donald Trump withheld nearly $400 million in military aid to Ukraine until Kyiv dug into political rival Joe Biden. Taylor's explosive testimony is said to have focused on his mounting alarm over the alleged “irregular, informal” diplomatic back-channeling — as well as on the transactional approach to relations with Ukraine, as described to him by Gordon Sondland, the U.S. Ambassador to the EU.
Why is his testimony valuable? Observers say Taylor's recollection, supported by contemporaneous notes, amounts to the most detailed rebuttal of White House claims that Trump did nothing wrong in his dealings with Ukraine.
