Washington • Fiona Hill, a former top National Security Council expert on Russia, was testifying to Congress behind closed doors Monday, the latest former Trump administration official to be subpoenaed as part of the House impeachment inquiry into President Donald Trump.
Hill wouldn't comment as she arrived on Capitol Hill, but her attorney said she had received a congressional subpoena and would "comply and answer questions" from lawmakers. She resigned from the White House National Security Council over the summer.
She is the first White House official to appear as part of the House impeachment inquiry .
