Democrats say they do not know what to do with his resignation and whether he will assist in their investigation.
"We, as Congress, need to get his travel records and the places he traveled, the persons he spoke with," said reporter Marcie Captur (D-Ohio), who chairs the subcommittee on budgets responsible for financing of DOE. "I believe Secretary Perry is a patriot. I have no idea what he's trapped in if he's caught for something. "
Kaptur said that this morning she had sent a text message to Homeland Intelligence Chairman Adam Schiff (D-Calif.) Asking for his testimony from the secretary. She said Schiff had not responded since Friday lunch. An Intelligence Committee spokesman declined to comment on whether he would seek Perry's testimony.
Perry said in an interview Friday with Fox News that he would contact the Energy Department lawyer whether he would respond to a call from the Intelligence, Oversight and External Relations Committees. Congressional investigators asked him to provide documents related to his travels to the country and his interactions with other figures in the study, including Rudy Giuliani, President Trump's personal lawyer.
Rep. Gary Connolly (D-Va.), A senior member of the Oversight and Foreign Affairs Committees, said Congress would not abandon its efforts to obtain testimony and records from Perry amid his resignation.
"He appears to have played a more prominent role than we previously thought," Connolly told reporters. "The role he played is the role he played. Whatever his present condition, it doesn't matter. "
Other Republicans downplay the potential damage to Perry's reputation, even as they state that he should not be involved in the process.
"I'm not at all worried about Rick Perry's legacy," reporter Pete Olson (Texas) said in an interview Wednesday, before Perry's announcement that he would resign. "He has to do the best for Rick Perry and the country. I trust Rick. If he wants to testify, he will do so. If not, I will not assume that he will not want to participate in the witch hunt ̵
