This is demonstrably false.

Inflation is defined as an increase in the money supply faster than the value of the economy rises, causing the purchasing power of money to decline. Since the only institution that can increase the money supply is the Federal Reserve and not the White House, inflation cannot be caused by Trump and only can be caused by the Federal Reserve.

Inflation can only be caused by printing money, Trump does not print money therefore Trump does not cause inflation. Quod erat demonstrandum, bitch.

Of course Trump could print his own money by following the Constitution and issuing an executive order to the Treasury Department telling them to issue gold and silver backed certificates but the last president to try that was JFK and we all know what happened to him.
