Mike Bloomberg denies "buying" the 2020 Democratic nomination

Mike Bloomberg, one of the world's richest people, is pushing back against claims that he wants to buy the Democratic presidential nomination. In his first TV interview since joining the 2020 race, "CBS This Morning" co-host Gayle King spoke to him about how he’s paying for his campaign. The former New York City mayor also discussed his plan to fight gun violence. Bloomberg addressed the issue in Aurora, Colorado, on Thursday with the community that lost 12 people to a mass shooting in 2012.
