"A subpoena has been issued to compel his attendance. Simpson’s attorney has asserted that his client will invoke his Fifth Amendment rights in response to the subpoena," the Senate leaders said in a statement.
Simpson had been listed as a witness for a public Judiciary Committee hearing scheduled for Wednesday regarding oversight of the Foreign Agents Registration Act and "attempts to influence U.S. elections."
But a spokesman for Grassley said earlier Friday that they had not heard from Simpson, who was not expected to agree to testify.
Donald Trump Jr. and Paul Manafort, Trump's former campaign manager, were also listed as witnesses for the hearing. They have also not confirmed they will testify.
Grassley and Feinstein said Friday while they were not issuing subpoenas for the two, they "reserve the right to in the future."
"Both Donald Trump Jr. and Paul Manafort ... have agreed to negotiate to provide the committee with documents and be interviewed by committee members and staff prior to a public hearing," Grassley and Feinstein said.
Under committee rules, the committee can subpoena individuals by a vote of the full committee or when Grassley and Feinstein — as the committee's top two members — have an agreement.
