BREAKING via @CBSNews: Part of Trump's speech Thursday night will touch on previously unreported Chinese meddling in U.S. elections, sources told me. Some evidence shows Beijing compromised U.S. voter data -- and evidence the CIA knew about the action and didn't share that information with Trump during his first term, per sources. Cabinet officials are expected to be in the audience during his remarks. Among those invited are the heads of CIA, FBI, ODNI and DHS, as well as other agencies and staff. Some cabinet members will not be there due to scheduling conflicts, I'm told.
