Donald Trump said the U.S. has serious weaknesses in voting safety before a high profile speech.
He claims China fixed the 2020 vote, saying the result was corrupt.
He now plans to investigate more flaws ahead of the next mid‑term elections.
Trump also warned TV stations to air his speech without delay or risk losing their broadcast rights.
His talk will push voter fraud stories, not economy or other major issues.
Trump keeps saying votes were manipulated, though courts tossed every claim for no basis.
He repeats the allegation daily in interviews.
