We’re finally hearing some details of the whistleblower complaint that is being kept from Congress by the new Director of National Intelligence. Rep. Adam Schiff has demanded that the complaint filed by a U.S. intelligence operative be sent to Congress. But Joseph Maguire, the new national intelligence head, has refused to turn it over.

Wednesday night, The Washington Post reported the complaint involved Donald Trump’s communication with an unnamed foreign leader. The incident was reportedly a phone call.

“Trump’s interaction with the foreign leader included a “promise” that was regarded as so troubling that it prompted an official in the U.S. intelligence community to file a formal whistleblower complaint with the inspector general for the intelligence community, said the officials, speaking on the condition of anonymity because they were not authorized to discuss the matter publicly.“

The Post reports the allegations raise new concerns about how Trump handles sensitive information. From The Post:

“Intelligence Community Inspector General Michael Atkinson determined that the complaint was credible and troubling enough to be considered a matter of “urgent concern,” a legal threshold that requires notification of congressional oversight committees.“
