OH I see YOU want Obama to be charged for everything from the day he took office and Republican presidents from the day they take over the responsibility ( Oct 1st ) for the Budget and debt
Oct 1 2009 the debt was 10/01/2009 11,920,519,164,319.42 and on 09/29/2017 ( closest date the US Treasury has ) 20,244,900,016,053.51
an increase of 8.3 Trillion
and again IF in either way you want to figure it IF you use your 10.6 X 2 that is 21.2 Trillion
and IF you want to use the date Trump took office it was 01/20/2017 19,947,304,555,212.49 that is still less then double the debt
FACT is there have been ONLY two Presidents in the last 50 years to double the debt hey were BOTH Republicans , Reagan and Bush II
have a nice day
