A few armed Secret Service agents and a U.S. Coast Guard boat with a machine gun might seem like excessive security for a young boy's play date - but not if your name happens to be Barron Trump. The 10-year-old son of President-elect Donald Trump and wife Melania was spotted playing with a group of children at the Mar-a-Lago estate in Palm Beach, Florida where his family were spending Thanksgiving. Barron was being watched closely by several men who appeared to be Secret Service agents as he mingled with other children on the lawn at the back of his dad's luxury estate. At least three men were seen standing within feet of Barron the entire time and they followed the boy wherever he went. He was dressed in a pair of shorts, a shirt and a red baseball cap just like Trump's Make America Great Again campaign hat. At one point, Barron was seen waving and watching on as a coast guard boat sailed past him as he stood on the ocean wall.The boat had a guard stationed at the front of vessel armed with a massive machine gun as it patrolled back and forth in front of where Barron was playing. They were part of a contingent of 150 security personnel assigned to watch over the Trump family as they spent their first post-election holiday at the vacation retreat last week.
