Hope Hicks, former White House communications director and a member of President Trump's inner circle since the start of his 2016 campaign, is set to testify on Wednesday before the House Judiciary Committee in a closed-door hearing.

Democrats on the panel, who are investigating possible obstruction of justice by Trump, seek to question Hicks about five instances of potential obstruction described in Special Counsel Robert Mueller's report, in addition to allegations that Trump directed hush money payments to two women, Politico reports. Although the hearing will not be public, a transcript will reportedly be released within 48 hours. This is the first time a member of Trump's inner circle will be interviewed by a Democratically-controlled panel in their investigations into Trump, CNN notes.

The White House on Tuesday directed Hicks not to answer any questions related to her time in the administration, also saying that specific questions related to her time on the transition team would "likely implicate executive branch confidentiality interests" as well, The Hill reports.

ABC News reports that the committee "would not find it acceptable for Hicks not to answer any questions about her time in the White House," citing a committee aide, and The New York Times reports that Democrats are "prepared to contest such assertions on the spot." Democrats may, however, be able to get some answers from Hicks about her time on the Trump 2016 campaign.

Hicks previously testified before the House and the Senate in 2018 and would not answer questions about her time in the White House.

When asked by CNN's Manu Raju on Tuesday about the White House instructing Hicks not to answer questions about her time in the White House, House Speaker Nancy Pelosi (D-Calif.) simply responded, "Obstruction of justice."
