Rock musician John Mellencamp took a break from performing his classic song "Pink Houses" at a recent concert to criticize President Donald Trump's proposal to rename the Gulf of Mexico as the "Gulf of America." According to reports, Mellencamp paused mid-song to call the idea a "stupid f***ing idea" and made a gesture in reference to the president. The moment drew cheers from the audience. In response, the White House fired back, defending the executive order and criticizing the rocker. White House spokesperson Harrison Fields said in a statement that Mellencamp should stick to music instead of politics, adding that the president's action was about honoring American heritage. The Gulf of Mexico is an international body of water, and renaming it would require international recognition. Mellencamp, known for his political activism, has previously criticized Trump. The incident highlights the ongoing cultural divide over the president's policies.
