More details from whistleblower memo on Trump's Ukraine call revealed
CBS News is revealing details from a memo written by the whistleblower whose claims led to the House impeachment inquiry into President Trump. Mr. Trump has maintained the entire report is a "scam," pointing to the person being a registered Democrat. CBS News has learned the whistleblower has a prior working relationship with a current Democratic presidential contender, but lawyers say their client has never worked for or advised a political campaign or party.
