Taylor-Sondland texts
On October 3, 2019, it was revealed that Taylor had expressed, in text messages, concern that President Trump may have withheld aid to Ukraine unless they investigated his political opponent, Joe Biden. According to transcripts released by the house impeachment probe, Taylor on September 9, 2019 at 12:47:11 AM texted, "I think it's crazy to withhold security assistance for help with a political campaign."

Over four hours later, at 5:19:35 AM, in his response to Taylor, Gordon Sondland, the United States Ambassador to the European Union, responded that the charge is "incorrect." "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. The President is trying to evaluate whether Ukraine is truly going to adopt the transparency and reforms that President Zelensk'y promised during his campaign." He then suggested Taylor call the Executive Secretary of the United States Department of State about any concerns: "I suggest we stop the back and forth by text If you still have concerns I recommend you give Lisa Kenna or S a call to discuss them directly. Thanks."
