If the World Trade Organization doesn't "shape up," President Donald Trump told Bloomberg he would pull the United States out.

In a Thursday interview with Bloomberg, Trump again criticized the international trading group's treatment of the United States.

He told Bloomberg, "If they don't shape up, I would withdraw from the WTO."

The president's comments follow previous reports that Trump had told White House aides that he wanted to withdraw from the WTO.

But top Trump administration officials haven't been as eager to pull out of the global trade regulator. In July, Commerce Secretary Wilbur Ross told CNBC that talk to withdraw from the WTO was "a little premature."
