MS NOW host Lawrence O'Donnell went on an unhinged rant against President Donald Trump's youngest son, Barron Trump, for following in his father's "poor footsteps" by not signing up for the U.S. military, Wonderwall.com can report, as the war with Iran continues to escalate tensions in the region. Barron, who turned 20 on March 20, now joins siblings Eric Trump, 42, and Tiffany Trump, 32, as "military-age" members of the first family who have decided not to enlist, while their presidential papa notoriously dodged the draft by arguing he had bone spurs in his feet.
