(CNSNews.com) - Who leaked the transcript of Michael Flynn's telephone conversation with the Russian ambassador to the United States?
It's the only "obvious felony" to emerge from the whole Trump-Russia investigation, Rep. Devin Nunes (R-Calif.), chairman of the House intelligence committee, told Fox News's Maria Bartiromo on Monday morning.
"It is the one felony that's very, very serious, leaking the highest, most sensitive information that we have in our government that got leaked to multiple people...so this was spread all over Washington, which it had to be high-level officials in the Obama administration right before President Trump was sworn in to office and nothing's been done about that," Nunes said.
"So we've been chasing around Russian ghosts all over the country, all over the world, accusing people of things, spying on other Americans in the Trump campaign, found no collusion, have found no felonies except that you have this obvious felony of classified information that was leaked over a year ago, and nothing's been done about it.
"And this should not be very hard to figure out, right, because very few people would have had this information, and you know that this information had to only go to the top people. And then somehow within days, that information, that phone call, that transcript, gets leaked to some of the nation's top mainstream newspapers in this country, and you're telling me that DOJ and FBI can't find out who that is? It's not believable. So we're going to have to keep pressing to get them to investigate."
Flynn was forced out as President Trump's National Security Adviser shortly after taking the job because he told Vice President Mike Pence that he did not discuss sanctions with the Russian ambassador in a phone conversation weeks before Trump took office.
Someone familiar with the classified transcript of Flynn's conversation leaked what he said to The Washington Post and other news outlets.
According to The New York Times, officials familiar with the conversation said that Flynn "had never made explicit promises of sanctions relief, but that he had appeared to leave the impression it would be possible."
Flynn's conversation took place on the same day the Obama administration sanctioned Russia for interfering in the U.S. election by expelling dozens of Russian diplomats from the country.
Attorney General Jeff Sessions told Bartiromo a week ago that the leaking classified documents "is being investigated."
"I will say this, the last two years before I became Attorney General there were, each year, there were three open investigations of classified leaks. Now we have 27. We’re going after this aggressively."
Nunes said on Monday it doesn't seem like it would be very hard to find the leaker or leakers.
