Treasury Secretary Janet Yellen on Wednesday said she “misspoke” in an interview earlier this month when asked about a potential U.S. government review of Elon Musk’s purchase of Twitter, adding that such a probe could be appropriate.

In an interview with CBS News in Bali, Indonesia, in mid-November, Yellen said she saw “no basis” for launching an investigation into Musk’s purchase of the social-media company. As CBS noted, her comments came just days after President Joe Biden said the deal was worthy of being looked at on national security grounds.
