St. Patrick’s Day will soon be upon us, and Team Trump would like you to know that for just $50 you can purchase a green “Make America Great Again” hat embroidered with a symbol that has nothing to do with St. Patrick’s Day.

The hats went on sale last week in advance of the holiday, celebrated on March 17, and had a four-leaf clover — instead of a three-leaf shamrock — stitched on the back. A four-leaf clover is not a symbol of Ireland. It is just a plant.

On Wednesday afternoon the hats disappeared from Mr. Trump’s online store. A spokeswoman for Mr. Trump did not respond to questions about why the hats were taken off the website.
