Throughout his turbulent ride to the White House, one constant for Trump was his family. Now, as he take oath to become the 45th President of the US, some of them will be coming with him in key roles to the White House. It's causing speculation about how that will affect the Trump administration. "I love you and I thank you, and especially for putting up with all of those hours. This was tough," Trump said. Unlike previous presidents with younger children, Trump's four adult children will play key roles in his administration and his youngest son Barron (10) won't even live at the White House (he will remain with his mother Melania at their gilded penthouse in Trump Tower so as not to affect his schooling).
