Former Acting Attorney General Sally Yates will testify on the investigation into Russia’s interference in the 2016 election.
Yates will testify on May 8 before a Senate Judiciary subcommittee.
President Trump fired Yates earlier this year for refusing to defend in court his original executive order restricting entry to the U.S. for refugees and people from certain Muslim-majority countries.
Earlier this month, the House Intelligence Committee asked several Obama administration officials, including Yates, to testify publicly in the panel’s probe into Russian interference in the election.
Former CIA Director John Brennan and former Director of National Intelligence James Clapper were also invited to testify with Yates.
The open panel, including Yates, had previously been scheduled in March but was canceled by committee Chairman Devin Nunes (R-Calif.).
The Washington Post reported earlier this month that the White House sought to block Yates from testifying, a charge White House press secretary Sean Spicer has denied.
The week before Yates had been scheduled to testify, Comey confirmed the existence of the FBI’s investigation into ties between members of Trump’s presidential campaign and Russia in an open hearing.
Yates first alerted the White House that former national security adviser Michael Flynn had misled Vice President Pence about the content of his calls to the Russian ambassador. The public revelation of those calls led to Flynn’s ouster in February.
