The Guardian confirmed that former president Donald Trump’s oldest daughter, and former senior White House adviser, will speak to the panel virtually.
Her testimony will come after that of her husband and fellow former presidential adviser, Jared Kushner, who spoke to the panel for more than six hours last week.
After Kushner’s testimony, Jamie Raskin, a Maryland Democrat and a member of the committee, told the Guardian: “There’s a momentum to this process when there’s cooperation. When people see that others are doing the right thing, it gives them the courage to do the right thing.”
A bipartisan Senate report linked seven deaths to the attack on the US Capitol on 6 January 2021, by supporters Donald Trump told to “fight like hell” in service of his attempt to overturn his defeat by Joe Biden.
Trump was impeached for inciting an insurrection but acquitted when enough Republican senators stayed loyal.
The House’s January 6 committee includes two Republicans, Liz Cheney of Wyoming and Adam Kinzinger of Illinois.
As the Guardian reported this week, the committee has identified Ivanka Trump as a senior adviser who would have known her father’s attempt to block certification of electoral college results at the Capitol was unlawful.
Referring to a law professor who presented the plan to block certification, a federal judge recently said it was “more likely than not that President Trump and Dr [John] Eastman dishonestly conspired to obstruct the joint session of Congress on January 6 2021”, and thereby committed multiple felonies.
Also in Washington on Tuesday, Enrique Tarrio, a former leader of the far-right Proud Boys group, pleaded not guilty to felony charges including conspiracy to block the certification by Congress of electoral college results on January 6. Five other members of the group have pleaded not guilty to the charge.
The January 6 committee also hopes Ivanka Trump might help explain a more-than seven-hour gap in White House call logs for the day of the Capitol attack.
Ivanka Trump’s role in her father’s administration has long been a lightning rod for controversy. On Monday, the watchdog group Citizens for Responsibility and Ethics in Washington (Crew) said: “Here’s a question Ivanka Trump can answer: how did she and Jared make up to $640m while working ‘for free’ in the White House?”
