New York Times reporter Maggie Haberman appeared on CNN Thursday to talk about the multiple legal problems facing former President Donald Trump, and she said that Trump should be particularly worried about efforts to flip longtime Trump Organization Chief Financial Officer Allen Weisselberg.

Reacting to reports that the Manhattan District Attorney's Office is zeroing in on getting Weisselberg to potentially cooperate in its criminal investigation of Trump, Haberman explained why he's such an important figure to the president's financial dealings.

"[Weisselberg] knows where every secret is buried financially, and some not financial," she explained. "And he was somebody who, in the Southern District of New York, when the federal prosecutors were going after Michael Cohen... Weisselberg was given limited immunity in order to testify against Cohen."

CNN host John Berman then asked Haberman "what would it take" Weisselberg to "turn" on Trump and cooperate as a witness in the Manhattan DA's investigation.

"I think it would take a lot, a presentation of very serious charges," she said. "I think it would take a presentation of charges not just against him, but against his sons, who they have also been asking at least one witness some questions about."
