United States Secretary of Homeland Security (2017).
On December 7, 2016, it was reported that then-President-elect Donald Trump nominated Kelly to be the fifth United States Secretary of Homeland Security.
On January 20, 2017, Kelly was confirmed as Secretary of Homeland Security by the United States Senate with a vote of 88-11. On that evening he was sworn in by Vice-President Pence.
White House Chief of Staff (2017–2019).
On July 28 2017, he was appointed to replace Reince Priebus as White House Chief of Staff.
Early into his tenure, media outlets such as "The New York Times", "The Washington Post" and FiveThirtyEight speculated that Kelly would bring moderation and discipline to the White House. In August 2017, early into Kelly's tenure, the "Washington Post" wrote that Kelly had "left no discernible imprint on the White House's philosophy" and that it was unclear if he would bring calm and rigor to the White House.
On December 8, 2018, Trump announced that Kelly would be leaving the position by the end of the year. He left the office on January 2, 2019.
Personal life.
Kelly is married to Karen Hernest. They have three children.
In 2010, Kelly’s 29-year-old son, First Lieutenant Robert Kelly, was killed in action when he stepped on a landmine while leading a platoon of Marines on a patrol in Sangin, Afghanistan. Robert Kelly's death made John Kelly the highest-ranking military officer to lose a son or daughter in Iraq or Afghanistan.
