Why it matters: Smith and his team are pulling out everything they can muster to persuade the courts that their case against Trump should go forward.
The new details: A White House staffer overheard Trump telling family members, "it doesn't matter if you won or lost the election. You still have to fight like hell," according to Smith's filing.
The common theme in all of that new evidence is to draw a brighter line between Trump's personal and official conduct.
The other side: Trump's attorneys will have the chance to file a response to Smith's brief, but the most damning retort has already been written -- by the Supreme Court.
Chutkan's ultimate decision will likely be appealed, perhaps all the way back to the Supreme Court, which has already ruled against Smith once.
What to watch: Trump is again laying the groundwork to deny the results of the 2024 election, promoting a similar catalog of baseless fraud claims that Smith cites in his filing.
