Former President Donald Trump named Sen. JD Vance of Ohio as his running mate on Monday, choosing a onetime critic who became a loyal ally and is now the first millennial to join a major-party ticket at a time of deep concern about the advanced age of America’s political leaders. “After lengthy deliberation and thought, and considering the tremendous talents of many others, I have decided that the person best suited to assume the position of Vice President of the United States is Senator J.D. Vance of the Great State of Ohio," Trump said in a post on his Truth Social network. The 39-year-old Vance rose to national fame with the 2016 publication of his memoir, “Hillbilly Elegy.” He was elected to the Senate in 2022 and has become one of the staunchest champions of the former president’s “Make America Great Again” agenda, particularly on trade, foreign policy and immigration. https://www.9news.com/article/news/nation-world/trump-vice-president-running-mate-pick-2024/507-1a7bc15f-dc9c-47b2-b854-9d79ed87fe99 More local videos here: https://bit.ly/2Pa0d1l Subscribe to NEXT: http://bit.ly/2eP1GwI Stay connected: 9NEWS Website: http://www.9news.com/ Facebook: https://www.facebook.com/ilike9news Twitter: https://twitter.com/9NEWS Instagram: https://www.instagram.com/9newsdenver/ Download the 9NEWS App: https://www.9news.com/appredirect/ Sign up for the 9NEWSLETTER: https://www.9news.com/email 9NEWS (KUSA) is located in Denver, Colorado.
