An expert witness has presented an analysis of cell phone data and Twitter activity from phones used by Donald Trump and his aide during his federal election interference trial. The expert determined how the phones were used in the post-election period, including on January 6th, 2021, and specifically identified when Trump's phone was unlocked and when the Twitter app was open on January 6th. Two other expert witnesses will provide testimony related to interpreting location data and analyzing location histories from Google, to help the jury understand the movements of individuals toward the Capitol on January 6th. Trump's federal election interference trial is scheduled to begin on March 4th, 2024.
