Senior State Department Official Appears Before Trump Impeachment Probe Reuters WASHINGTON - A top U.S. State Department official on Wednesday appeared before the impeachment probe into President Donald Trump, the first witness to show up this week after a string of administration officials refused to meet with investigators. David Hale, who was appointed by Trump as under secretary for political affairs, met behind closed doors with lawmakers who are leading the probe of Trump in the Democratic-controlled House of Representatives. More details in the impeachment inquiry are expected to be released on Wednesday, a day after transcripts revealed a top Trump donor-turned-diplomat reversed course and told investigators Ukrainian aid was tied to investigations of political rivals sought by the U.S. president. On Tuesday, publicly released transcripts showed U.S. ambassador to the European Union Gordon Sondland had returned to give lawmakers new details after his memory was "refreshed," corroborating other witnesses who said Trump sought to pressure the Ukrainians into launching investigations that appeared aimed at boosting his 2020 re-election campaign.
