The newest addition to the Trump circle made her official political debut Saturday night, as Trump’s granddaughter Kai and daughter Ivanka appeared radiant at Inauguration events. Bettina Anderson – whose romance with Don Jr, 46, was first revealed by DailyMail.com last summer – joined the family’s pre-inauguration celebrations at Trump National Golf Club in Sterling, Virginia. Anderson, 38, who has maintained a relatively low profile since the exclusive report on her relationship with the former first son, appeared in a Trump family photo as they gathered for a fireworks display ahead of Monday’s swearing-in ceremony.
