President Donald Trump said on Sunday that actions by the U.S. Federal Reserve have nicked U.S. economic growth and stock market gains by perhaps 30 percent, and that it should begin pumping money into the economy as it did during the 2007-2009 recession.

Trump's latest broadside against the central bank, delivered by Twitter and without citing any evidence, came as European Central Bank head Mario Draghi and other international officials worried that a Fed politicized by potential Trump nominees would rattle a dollar-based global system.

"If the Fed had done its job properly, which it has not, the Stock Market would have been up 5000 to 10,000 additional points, and GDP would have been well over 4 percent instead of 3 percent...with almost no inflation," Trump said.
