The White House will not assert executive privilege for testimony by former US president Donald Trump's daughter and son-in-law and former advisers, Ivanka Trump and Jared Kushner, before the January 6th committee.
Communications director Kate Bedingfield confirmed the decision on Tuesday.
Speaking to reporters at the White House, Ms Bedingfield said president Joe Biden has been clear "the constitutional protections of executive privilege should not be used to shield from Congress or the public information about an attack on the Constitution itself".
Investigators probing the January 6th insurrection at the US Capitol have identified a roughly eight-hour gap in official records of then-president Donald Trump’s phone calls as the violence unfolded, and his supporters stormed the building, sources have revealed.
The gap extends from just after 11am to about 7pm on January 6th, 2021, and involves White House calls, according to someone familiar with the investigation.
It is unclear if that gap includes White House mobile phones.
It is widely known that Mr Trump had conversations on January 6th with Republican legislators.
Investigators in the US House of Representatives are looking at whether the former president was communicating during that time through other means, possibly through personal mobile phones, or some other type of communication – such as a phone passed to him by an aide or a burner phone.
