WASHINGTON — A previously canceled House Intelligence Committee hearing to receive testimony from three former top Obama administration officials about Russia’s attempts to influence the 2016 election is back on for next month.

The panel said Friday it had invited Sally Yates, the former acting attorney general fired by President Donald Trump, former Director of National Intelligence James Clapper and former CIA Director John Brennan, to testify sometime after May 2 in an open hearing after their original testimony was abruptly canceled in March by Chairman Devin Nunes, R-Calif.

The announcement indicates that the panel’s Russia investigation, which was thrown into turmoil last month after Nunes stepped aside as head of the probe following allegations he may have improperly disclosed classified information, is getting back on track.

Rep. K. Michael Conaway, R-Texas, took over as head of the investigation after Nunes’ decision.

A committee news release Thursday also said FBI Director James Comey and Adm. Mike Rogers, the head of the National Security Agency, would testify in a closed session May 2.

Nunes’ decision to call off the original hearing with Yates, Brennan and Clapper came only days after the committee’s first public hearing in which Comey confirmed that the bureau was investigating Russia’s ties to Trump’s associates.

Nunes stepped aside as head of the Russia investigation after the leaders of the House Ethics Committee said it is investigating whether Nunes improperly disclosed classified information, apparently when he held a news conference last month to claim that Trump associates’ names had been revealed in intelligence reports.

Nunes has denied wrongdoing.
