US President Donald Trump is expected to allege previously unreported Chinese interference in US elections during a primetime address on Thursday, including claims that Beijing compromised US voter data and that the CIA was aware of the activity but did not inform him during his first term, according to a report by CBS News, citing sources familiar with the matter.

President Trump is expected to address declassified intelligence on 2020 election interference, though details remain murky ahead of time.

“It doesn’t get bigger, because without free and fair elections, you don’t have a country,” Trump said earlier this week when previewing the address.
