Specifics about former President Donald Trump's efforts to keep secret the support from his White House for overturning his loss of the 2020 election were revealed in late-night court filings that detail more than 700 pages of handwritten notes, draft documents and daily logs his top advisers kept related to January 6.

The National Archives outlined for the first time in a sworn declaration what Trump wants to keep secret.

And the US House has told a federal court that Trump has no right to keep confidential more than 700 documents from his presidency, citing a committee's need to reconstruct Trump's efforts to undermine the 2020 election and his actions on January 6.

The court filings are in response to a lawsuit Trump brought nearly two weeks ago in which he is attempting to block congressional investigators from accessing hundreds of pages of records they requested from the National Archives, which inherited Trump's presidential papers. The House presents itself as in agreement with the Biden administration, in an unusual show of inter-branch alignment, to oppose Trump.
