Ohh, that's the reason for the “former Obama administration official” line (as well the usual everything-is-Obama-and-the-Clintons'-fault, obvs).
"Obama fired Flynn as head of the Defense Intelligence Agency in 2014 and warned Trump against hiring him.
"A report from CNN quoting unnamed White House officials as claiming that the Flynn-Kislyak contacts had been authorized by the Obama administration drew derision from former staffers.
"Ned Price, the former National Security Council spokesman told the Guardian in an email: 'There is no world in which the Obama administration would have authorized anyone to attempt to subvert the principle of "one President—and one foreign policy—at a time."'
“'Any suggestion otherwise by this White House is laughable, as are their other attempts to distance themselves from Michael Flynn, President Trump’s first and handpicked National Security Advisor,' Price said."
