It happened here.
In the indictment, Smith included a speech made by Trump. But he knowingly, willfully and with malice left out key parts of Trumps speech. Simply left it out.
Alan Dershowitz - "lying by omission, under the law, can be just as serious as lying by commission And Jack Smith knowingly doctored Trumps words, without doctoring it, it moves Trump's speech into the territory of the 1st amendment. You can argue that, but you cannot argue that Smith didn't lie."
It's provable. It's right there in the false indictment he created.
