Fox News correspondent Peter Doocy left White House press secretary Karine Jean-Pierre stumbling on her first official day behind the lectern after Jen Psaki's departure.

The topic? Inflation and President Joe Biden's claim that raising corporate taxes will help the ongoing economic crisis.

What happened?

Referring to a tweet that Biden published last week, Doocy lobbed a softball question at Jean-Pierre, "How does raising taxes on corporations reduce inflation?"

But the new press secretary appeared unaware that such a tweet from Biden existed, asking if Doocy was, in fact, referring to a specific tweet.

When Doocy informed her that Biden's official Twitter account made such a connection between corporate taxes and inflation last week, Jean-Pierre stumbled her way through recycling Democratic talking points about taxes and corporations paying their "fair share."
