WASHINGTON (NEXSTAR) -- In an effort to save TikTok, President Donald Trump, who has gained 15 million followers on the app since last year, is pressuring China to sell half the company to the United States. After signing an executive order Monday extending TikTok’s sale deadline by 75 days, Trump called his offer a “joint venture.” He says the deal on the table would give the U.S. 50% ownership of TikTok and allow him to find an American buyer. So far, China has signaled openness to a deal with the Trump administration, which is threatening to impose tariffs if they decline. On Monday, Chinese Foreign Ministry spokeswoman Mao Ning said business operations and acquisitions, “should be independently decided by companies in accordance with market principles.” “Sounds like a good deal to me,” Trump said. “The United States will make it very worthwhile for them." The president says he would be open to selling the massive platform to tech billionaire Elon Musk or others. On Wednesday, Rep. Pete Aguilar (D-Calif.) said he was unclear on what Trump meant by “joint venture.” “I'm not aware of what the specifics are that the administration is talking about. I don't think any Republicans are,” Aguilar said. Aguilar says that, bottom line, the law requires TikTok’s Chinese parent company to divest or be banned in the U.S. Last week, the Supreme Court unanimously upheld the law, citing Congress’ concerns over national security. Sen. Josh Hawley (R-Mo.) said he would not object to Musk buying TikTok but insisted the app must cut ties with Beijing. “That is the sole criteria, and that is the only criteria in the law,” Hawley said. Because of U.S. antitrust laws, Hawley said he doubts Google or Meta would be eligible to purchase TikTok, which has roughly 170 million American users.
