Story highlights Warner put the blame on the Trump administration

House oversight says Flynn may have committed a crime

Washington (CNN) The top Democrat on the Senate intelligence committee knocked former national security adviser Mike Flynn and the Trump administration over his failure to disclose foreign payments he had received.

"There seems to be no evidence that the Trump administration did appropriate due diligence before they brought him into this very senior position," Virginia Sen. Mark Warner said on CNN's "Erin Burnett OutFront."

Warner's comments in the Thursday interview came after top House Oversight Committee Democrat Elijah Cummings revealed both that the Defense Intelligence Agency warned Flynn not to accept foreign payments in 2014 and that the Department of Defense's inspector general had opened an investigation into Flynn.

Flynn was ousted from his role as President Donald Trump's national security adviser after reports surfaced of him misleading Vice President Mike Pence about communications between himself and Russian ambassador Sergey Kislyak. Additionally, the House oversight committee said on Tuesday that Flynn may have broken the law by not properly disclosing payments from Russia and Turkey.

Saying Flynn had exhibited a "pattern of behavior," Warner said this was cause for real concern and tied the entire matter to issues with the Trump administration.
