2. She forgot to wish her sister on her birthday
Tiffany is the Trump everyone seems to forget about, including her own family. Although she wished Donald on his birthday, she was snubbed by everyone on her own birthday. There were no wishes from Ivanka or Donald and even the official White House seemed to let her birthday slide by without acknowledging it. This seemed like a deliberate snub, as Ivanka and her father are pretty accustomed to wishing their friends and family members on their social media.
