Democrats have called the testimony the most damaging account yet, as Taylor provided an "excruciatingly detailed" opening statement, according to the New York Times.

(We're still waiting on a leak - or at least a transcript, from Ukraine special envoy Kurt Volker, whose testimony earlier this month was reportedly exonerating). 

Taylor notably expressed his concerns in a Sept. 9 text message to US ambassador to the EU, Gordon Sondland, saying: "I think it's crazy to withhold security assistance for help with a political campaign."

To which Sondland replies "Bill, I believe you are incorrect about President Trump's intentions. The President has been crystal clear no quid pro quo's of any kind," adding "I suggest we stop the back and forth by text."  

On Tuesday, Mr. Taylor directly addressed accusations surrounding Ukraine's president, Volodymyr Zelensky, and Burisma, a Ukrainian gas company that employed Hunter Biden, the son of former Vice President Joseph R. Biden Jr., one of the leading Democratic candidates for president.

He "drew a very direct line in the series of events he described between President Trump's decision to withhold funds and refuse a meeting with Zelensky unless there was a public pronouncement by him of investigations of Burisma and the so-called 2016 election conspiracy theories," Ms. Wasserman Schultz said. -New York Times
