Hope Hicks, once a close aide and communications director for President Donald Trump, will become on Wednesday the first member of his inner circle to testify to the congressional panel leading a probe into possible obstruction of justice by Trump.
Democrats who control the U.S. House of Representatives Judiciary Committee believe Hicks can provide important insights into five episodes of potential obstruction by Trump that were described in former special counsel Robert Mueller's report on Russian meddling in the 2016 presidential election.
They also expect Hicks to shed light on alleged hush payments during the campaign to two women who said they had affairs with Trump, including porn star Stormy Daniels. Trump has denied the affairs.
