Under Armour CEO Kevin Plank on Wednesday published a full-page ad in his hometown newspaper, The Baltimore Sun, that walked back his previous comments praising President TrumpDonald John TrumpForget the spin: Five unrefuted Mueller Report revelations Lara Trump: Merkel admitting migrants 'one of the worst things that ever happened to Germany' Financial satisfaction hits record high: survey MORE.

The ad, which states the company is "publicly opposing the travel ban," appeared to be in response to comments Plank made earlier this month on CNBC, calling Trump "an asset to the country" and a "pro-business president."

“To have such a pro-business president is something that is a real asset for the country. People can really grab that opportunity. He wants to build things. He wants to make bold decisions and be really decisive," Plank said in the interview.

The comments sparked a boycott by some against Under Armour, including criticism from celebrities such as Dwayne "The Rock" Johnson.

"In a business television interview last week, I answered a question with a choice of words that did not accurately reflect my intent," the ad, addressed to Baltimore, reads. "I want to clarify to our hometown exactly the values for which Under Armour and I stand."

While the letter never directly mentions Trump, it says the company stands for equal rights, praises immigration as a "source of strength, diversity and innovation," and comes out against Trump's executive order on immigration and refugees.

"I personally believe that immigration is the foundation of our country's exceptionalism," Plank wrote.
