House Democrats Set To Subpoena Ambassador Sondland

Gordon Sondland, the U.S. ambassador to the EU, did not attend a congressional interview as instructed by the State Department and White House. His absence is part of a broader impeachment inquiry into President Trump, which House Republicans criticize as biased. The inquiry involves allegations of a quid pro quo with Ukraine, as highlighted in a whistleblower complaint. Text messages between Sondland and other officials are central to the investigation. Despite requests, the State Department is withholding key documents. Democrats argue that the lack of cooperation is evidence of obstruction of Congress.
