A look at some of the remarks in the second round of public hearings in the impeachment inquiry by the House Intelligence Committee:
Trump and his personal lawyer, Rudy Giuliani, have defended their actions in asking Ukraine to investigate the Bidens by citing a video of Joe Biden from 2018. Speaking on a public panel, Biden recounted threatening to withhold a $1 billion loan guarantee from Ukraine's government unless it fired the prosecutor who the U.S. and other countries said was failing to fight corruption.
Trump and his GOP allies are suggesting that the whistleblower’s complaint is false, and so the person has vanished. But key details have been corroborated by people with firsthand knowledge of the events who have appeared on Capitol Hill.
