Obama’s former Deputy Assistant Secretary of Defense, Evelyn Farkas, made a bombshell admission on MSNBC: the Obama Administration was spying on Donald Trump.

Farkas was commenting on the ongoing investigation between Donald Trump and his ties to Russia—but wound up accidentally confirming Trump’s startling accusation that the Obama White House had set up surveillance on him.

“I was urging my former colleagues and… the people on the Hill… [to] get as much information as you can, get as much intelligence as you can, before President Obama leaves the administration,” said Farkas, in an interview with MSNBC’s Mika Brzezinski. “Because I had a fear I had a fear that somehow that information would disappear with the senior [Obama] people who left. So it would be hidden away in the bureaucracy.”

Farkas explained that, after the Obama Administration had received intelligence that Trump’s team might be talking to Russia, she urged her friends in the White House to leak as much intelligence as possible—because, once Trump was inaugurated, it would be far harder to link him and his associates to Russia. Leaking classified documents is a federal crime.

But then, Farkas accidentally dropped an even bigger bombshell. She admitted that she was also afraid that the incoming Trump Administration, once they took charge of the executive branch, would figure out that the Obama Administration was spying on them—and they took efforts to cover their tracks.

She added: “If [Trump’s staff] found out how we knew what we knew about… [their] dealing with Russians, that they would try to compromise those sources and methods, meaning we no longer have access to that intelligence. So I became very worried because not enough was coming out into the open and I knew there was more…”

Trump attracted huge controversy for his assertion earlier this month that Obama had wiretapped his campaign team during the 2016 presidential election. While “wiretapping” may not be the right word, more and more evidence continues to come out that Obama and his staff had, in fact, been surveilling Trump’s campaign.

A congressional investigation into the illegal surveillance is ongoing. It’s unclear whether or not they’ve contacted Farkas about her role.
