Former FBI Director James Comey may not be done testifying on Capitol Hill.
Top lawmakers on the Senate Judiciary Committee are weighing whether to subpoena the former FBI chief to testify before their panel.
"He asked me and I said I would," Feinstein said Thursday when asked by The Hill if she and Grassley had discussed a subpoena. 
Feinstein made the comments after Comey's testimony before the Senate Intelligence Committee, of which Feinstein is also a member.
Pressed if they had discussed a timeline, Feinstein deferred to Grassley, noting, "He's the chairman; he'll make that decision."
Comey gave his first public comments since he was fired in May before the Intelligence Committee but has so far refused to appear before the Judiciary panel, which has oversight of the FBI.
Grassley raised the prospect of subpoenaing Comey to testify before his committee on Wednesday. Members of his panel have clamored since last month to hear from the former director.
"Under our rules on our committee, if Sen. Feinstein would agree to subpoena, I would," Grassley, the chairman of the committee, told CNN ahead of Comey's testimony Thursday.
A spokesman for Grassley noted after Comey's testimony that "no specific decisions on issuing subpoenas have been made at this time."
"Senator Grassley is willing to consider issuing subpoenas in the course of the Judiciary Committee’s ongoing and bipartisan oversight. ... He’ll need to work toward an agreement with the Ranking Member on which types of subpoenas they might issue to which recipients and in what order. That all depend on the course of the investigation," the spokesman said. 
The Judiciary Committee has the ability to subpoena an individual or information, according to the committee's rules, if either Feinstein and Grassley can come to an agreement or if it's approved by a vote of the full committee. 
Both the Senate Judiciary and Intelligence committees are conducting separate investigations into Russia's election interference, including potential ties between President Trump's campaign and Moscow. They are also probing Comey's firing.
Grassley said in a statement that Comey's testimony "left many questions unanswered and even raised some new questions about the decisions he’s made in the course of handling politically-charged investigations."
