During Barack Obama’s presidency, the U.S. total outstanding debt increased by almost $8.34 trillion, the biggest dollar increase of any president. In terms of percentage change, Abraham Lincoln’s term had the highest increase at 2,860%, increasing the U.S. debt from about $90.6 million in 1861 to $2.68 billion in 1865 when he was assassinated.
So to answer your question, No, President Trump will not bankrupt the U.S. economy. Now if a left wing socialist President like Barack Hussein Obama should be elected again, than bankruptcy is a possibility.
