The closed-door testimony by the United States senior diplomat in Ukraine significantly changes the discussion about whether President Trump withheld military assistance to compel a foreign government to investigate one of his political rivals.
It is no longer a question of whether this happened. It is now a question of how the president explains it and how lawmakers especially Republicans choose to respond to it.
The lengthy prepared testimony by William B. Taylor Jr. to the House Intelligence Committee is painstakingly clear in its rendition of events. His account directly contradicts the president and asserts that military assistance was withheld for months as Trump was demanding an explicit statement from Ukraines President Volodymyr Zelensky confirming that he would launch investigations the president wanted.
