In the past, Walmart has issued statements after these incidents saying: "This item was sold by a third-party seller on our marketplace and clearly violates our policy".
Walmart's marketplace, which was created to compete with a similar program by Amazon, now has about 18,000 sellers and the retail giant receives a percentage of each sale, according to Bloomberg News. While it can't entirely deny responsibility, its failing here has nothing to do with partisan politics.
It was sold on its marketplace, which features products by many brands, and includes political t-shirts representing many different points of view. And the store in 2015 announced it would no longer sell items promoting the Confederate Flag.
When News4Jax searched the link the apparel was found on, it appeared to have been taken down. "We removed it as soon as it was brought to our attention, and are conducting a thorough review of the seller's assortment". They do so in violation of their agreement, but quite often they escape unnoticed.
Walmart has not commented on the merchandise. Alibaba's e-commerce platform Taobao is so plagued by fakes that the United States has labeled it a "notorious market" for counterfeits. The company isn't pushing a liberal, anti-Trump agenda; it's just trying to get people to buy clothes. There was also a baby onesie being sold with the same logo.
As of early Tuesday morning, the "Impeach 45" clothing was still available on Walmart's website. The company also sells a wide range of pro-Trump merchandise, including a substantial number of "Make America Great Again" hats. Walmart may not know about them, either.
