Trump campaign manager links Nike factories to Duke basketball star's injury

President Trump's 2020 campaign manager on Thursday linked Nike factories not being in the U.S. to the injury of Duke Basketball player's Zion Williamson.

"Maybe it is time for @Nike to bring factories back to the US where quality manufacturing will protect our athletes," Brad Parscale wrote on Twitter.

The Duke star and consensus top pick for the upcoming NBA draft left the school's game against rival North Carolina with a knee injury Wednesday night after his shoe tore when he planted his foot.

The injury was diagnosed as a minor knee sprain, meaning Williamson is likely able to return this season.

Nike, a longterm supplier of shoes and other equipment to Duke, said in a statement that the injury was an "isolated incident" but that the company would work to determine the cause of the shoe breaking apart.

"We are obviously concerned and want to wish Zion a speedy recovery," Nike told ESPN in a statement. "The quality and performance of our products are of utmost importance. While this is an isolated occurrence, we are working to identify the issue."

Nike's over 500 factories are spread around the world.

The Trump administration has frequently called for U.S. companies to bring their manufacturing back to the country.
