Ex-Ukraine envoy who Trump called 'bad news' to testify in impeachment probe

The former U.S. ambassador to Ukraine who Donald Trump has called "bad news" was due to testify on Friday in the U.S. House of Representatives impeachment inquiry into the president, while another U.S. envoy agreed to testify next week even as the White House sought to stonewall the investigation.
