CBS News has confirmed former New York City Mayor Michael Bloomberg is actively working to get on the 2020 ballot in at least one state. The billionaire was asked about a possible run last week by "Face the Nation" moderator Margaret Brennan. He said “nothing’s changed” since he put out a statement in March outlining why he wasn’t running for president. Brennan joins “CBS This Morning” to discuss 2020, the impeachment inquiry into President Trump, and “Face the Nation’s” 65th anniversary.
