President George W. Bush - President Bush added the most to the debt, more than $6 trillion. This more than doubled the debt, which was $5.8 trillion on September 30, 2001 -- the end of FY 2001, which was President Clinton's last budget. Bush responded to the 9/11 attacks by launching the War on Terror. This drove military spending to record levels, $600-$800 billion a year. This included the
Iraq War, which cost $807.5 billion. President Bush also responded to the 2001 recession by passing
EGTRRA and
JGTRRA, otherwise known as the
Bush tax cuts, which reduced revenue. He approved a $700 billion bailout package for banks to combat the 2008 global financial crisis. For more, see the
