The $1.9T stimulus package to support the U.S. recovery from the effects of the COVID-19 pandemic may have contributed "a little bit" to the elevated inflation that followed, Treasury Secretary Janet Yellen told CNBC in an interview.

Janet Yellen discussed inflation, the Covid-19 pandemic, the Fed, DOGE and more on CNBC's "Money Movers" in an interview before leaving her role.

Treasury Secretary Yellen, after years of denying or ducking the issue, is conceding that President Biden’s Covid-19 stimulus package contributed to the soaring prices of the past four years but insists its impact was minimal.
