A growing number of Democrats have shown support for beginning an impeachment inquiry, spurred by recent reports that a U.S. intelligence official filed a whistleblower complaint against the president last month.
Citing unidentified Democratic officials, the Washington Post, The New York Times and The Wall Street Journal reported Pelosi would back the move to begin a formal inquiry.
"I've said to people, 'As soon as we have the facts, we're ready,'" Pelosi said earlier Tuesday while speaking at The Atlantic Festival. "Now we have the facts. We're ready. For later today."
Pelosi is expected to speak publicly about the path forward at 5 p.m. EDT.

Trump announced Tuesday on Twitter that he authorized the release of a transcript of the conversation.
"You will see it was a very friendly and totally appropriate call," the president wrote.
