The stock market temporarily swung upwards in a matter of minutes after CNBC ran several chyrons falsely stating that President Donald Trump considered a 90-day pause on the tariffs.

Several outlets reported on the now-debunked 90-day pause after White House national economic council director Kevin Hassett told Fox News that Trump will “decide what [he’s] going to decide” on tariffs. Hassett touched upon this issue in response to billionaire Bill Ackman, who called for a 90-pause to prevent an “economic nuclear winter” due to tariffs.

“You know, I think the president is going to decide what the president is going to decide,” Hassett said on “Fox & Friends” Monday. “There are more than 50 countries in negotiation with the president, we’ve got the prime minister of Israel coming today, we’ve had a reach out over night from Taiwan, but I would urge everyone, especially Bill [Ackman] to ease up the rhetoric a little bit. The fact is that a 10% baseline tariff is on 14% of GDP. That’s how much trade we have, how many imports.”
