In recent weeks, the Trump Organization has ordered the manufacture of new tee markers for golf courses that are emblazoned with the seal of the president of the United States. Under federal law, the seal’s use is permitted only for official government business. Misuse can be a crime under 18 U.S. Code § 713.

Past administrations have policed usage vigilantly. In 2005 the Bush administration ordered the satirical news website The Onion to remove a replica of the seal. Grant M. Dixton, associate White House counsel, wrote in a letter to The Onion that the seal “is not to be used in connection with commercial ventures or products in any way that suggests presidential support or endorsement.”

Eagle Sign and Design, a metalworking and sign company with offices in New Albany, Indiana, and Louisville, Kentucky, said it had received an order to manufacture dozens of round, 12-inch replicas of the presidential seal to be placed next to the tee boxes at Trump golf course holes. Two tee markers are placed on the ground at the start of a hole on golf courses to indicate where golfers should stand to take their first swing.

“We made the design, and the client confirmed the design,” said Joseph E. Bates, who owns Eagle Sign, declining to say who the client was. But an order form for the tee markers reviewed by ProPublica and WNYC says the customer was “Trump International.” The Facebook page for Eagle Sign and Design shows a photo of the markers in an album with the caption “Trump International Golf Course.”

Just another Trump family illegality.
