Another Obama failure.

WASHINGTON — The Obama White House’s chief cyber official testified Wednesday that proposals he was developing to counter Russia’s attack on the U.S. presidential election were put on a “back burner” after he was ordered to “stand down” his efforts in the summer of 2016.

The comments by Michael Daniel, who served as White House “cyber security coordinator” between 2012 and January of last year, provided his first public confirmation of a much-discussed passage in the book, “Russian Roulette: The Inside Story of Putin’s War on America and the Election of Donald Trump,” co-written by this reporter and David Corn, that detailed his thwarted efforts to respond to the Russian attack.

They came during a Senate Intelligence Committee hearing into how the Obama administration dealt with Russian cyber and information warfare attacks in 2016, an issue that has become one of the more politically sensitive subjects in the panel’s ongoing investigation into Russia’s interference in the U.S. election and any links to the Trump campaign.

The view that the Obama administration failed to adequately piece together intelligence about the Russian campaign and develop a forceful response has clearly gained traction with the intelligence committee. Sen. Mark Warner, D-Va., the ranking Democrat on the panel, said in an opening statement that “we were caught flat-footed at the outset and our collective response was inadequate to meet Russia’s escalation.”

That conclusion was reinforced Wednesday by another witness, Victoria Nuland, who served as assistant secretary of state for Europe during the Obama administration. She told the panel that she had been briefed as early as December 2015 about the hacking of the Democratic National Committee — long before senior DNC officials were aware of it — and that the intrusion had all the hallmarks of a Russian operation.
