(CNN) A member of House Democratic leadership says it may be time to hear from Fox News host Sean Hannity -- under oath.

Rhode Island Rep. David Cicilline, who chairs the Democratic Policy and Communications Committee, said that Hannity's latest comments suggest he has information about hush money payments made by Trump's former personal attorney, Michael Cohen, to keep the then-presidential candidate's alleged extramarital affairs quiet in the days before the 2016 election. Trump later reimbursed Cohen for those payments.

"Sean Hannity volunteered first-hand knowledge about Michael Cohen's actions last night," Cicilline spokesman Francis Grubar told CNN. "If he was lying, it wouldn't be the first time. This is the same guy who claimed inside knowledge that Russia didn't hack the DNC until a federal judge ordered him to stop. Regardless, if he feels he has information that's relevant to this investigation, he should share it under oath before Congress."

On his television program Thursday night, Hannity told Trump that Cohen told him "at least a dozen times" that "he made the decision on the payments -- and he didn't tell you."

"He told me that personally," Hannity said to Trump.
