Trump makes last effort to keep hidden January 6 case evidence before election

Prosecutors asked permission to file public version of brief with references to testimony from Trump's closest aides

Donald Trump's lawyers made a last-ditch effort on Tuesday to limit the amount of evidence that could become public that special counsel prosecutors collected during their criminal investigation into the former US president's efforts to overturn the results of the 2020 election.

The prosecutors last week filed under seal a brief, which may be as long as 180 pages, to presiding US district judge Tanya Chutkan that defends the viability of the charges against Trump even after the US supreme court's presidential immunity ruling.
