Jared Kushner, former President Donald Trump’s son in law, appeared before the House committee investigating the Jan. 6, 2021 attack on the United States Capitol Building to testify about that day.

On Friday, NBC News reported that Kushner appeared before the committee a day earlier to share what he knew about how the White House responded to the Capitol Riot. According to one of the House investigators, Kushner elected to share what he knew about that day voluntarily and spoke for more than six hours.

“He was able to voluntarily provide information to us to verify, substantiate, and provide his own take on this different reporting,” Rep. Elaine Luria (D-Va) told MSNBC, adding that it was "really valuable" to have heard from Kushner.

By appearing before the House panel, Kushner has become the highest-ranking White House official as well as the first member of the Trump family to provide information to the Jan. 6 committee. On the day of the riot, Kushner was not physically present in the White House but he was tasked in the days leading up to it with the unceremonious task of trying to convince his father-in-law that he had lost the November 2020 election to now-President Joe Biden.

Kushner is not the only one within Trump’s inner circle to consider testifying or cooperating with the committee.

Last month, it was reported that Trump’s eldest daughter Ivanka was in talks about a voluntary appearance to share her knowledge of Jan. 6. Aides who worked for former-Vice President Mike Pence have also testified and furnished documents pertinent to the House’s investigation. Pence, whose relationship with Trump was ruptured by his refusal to go along with plans to sabotage Biden's electoral win, has yet to commit to cooperating with the panel.

However, other aides close to the former president have been resistant to testifying. Several, including former White House strategist Steve Bannon, have been held in contempt of Congress for refusing congressional subpoenas to provide information to the investigation.
