Not bad for a 40 year old dad of 5 who sits at a desk all week😂💪.” He went on to thank everyone who helped him achieve his goal, while adding that he looked “forward to the hate comments.” Despite splitting up, both Trump Jr. and Vanessa have maintained a cordial relationship — spending together at the president’s Mar-a-Lago estate in Florida and attending the White House Easter Egg roll together as a family earlier this spring. Vanessa also appeared to give her blessing to her husband’s new relationship — publicly confirming it on Twitter before even they did. Grant Lamos IV/Getty Vanessa made the revelation on Thursday afternoon, when she defended the new couple on Twitter against what she described as an “attack” by the New York Daily News. “The lengths people will go to attack a woman simply because she’s dating Don,” Vanessa, 40, tweeted. “We’ve been separated for over 9 months and respect each other’s decisions & privacy. We’ll focus on raising our great kids. Would be nice if the press did the same rather than obsess over our pvt lives!” Her comments come about a month after Trump Jr. publicly praised Vanessa on social media, calling her “the best mom in the world” in a Mother’s Day post.
