Well 8 trillion more since mr "I will pay off the national debt " came in to power.
To put it in perspective obama added 9 trillion in 8 years and he had to deal with the Bush recession.
By the way I was here in the usa when Obama was in power, my 401k did great, the S&p hit record highs.
That is what trump received, and he got us in to a dumpster.
