Former U.S. Ambassador to Ukraine to testify tomorrow

Marie Yovanovitch, the former U.S. Ambassador to Ukraine who was ousted earlier this year, will testify in a public hearing Friday. Multiple witnesses have accused President Trump's personal attorney, Rudy Giuliani, of engaging in a smear campaign against her. Political contributors Antjuan Seawright and Leslie Sanchez join CBSN to discuss the messaging tactics of both parties in the impeachment inquiry.
