Philip and her daughters were the last to leave the bus.The video shows the driver then run out of his bus and approach the woman."That's when spit landed on my face," she said. "I heard yelling. When I turned around, he spit in my face and he ran back to the bus."Philip says the driver was saying hurtful things to her."He was talking about baby father, 'You need to tell your baby father to get you a car. You don't need to be on my bus,'" she said.The MTA released the following statement:Philip admits she said things she now regrets, but is planning to sue the MTA after the spitting incident.----------
