Kellyanne Conway, counselor to President Trump, said today that she "did not know" whether the president and vice president were made aware three weeks ago that Michael Flynn, who resigned as national security adviser on Monday night, had misled the public and was possibly susceptible to blackmail because of his preinauguration conversations with Russia's U.S. ambassador.
Flynn resigned because his job had become "increasingly unsustainable," Conway said on "Good Morning America" today, attributing the incidents that led to his resignation to forgetfulness or misleading information.
She said that Flynn had a conversation with Vice President Mike Pence but that the information he gave at that time "turned out to not be true."
"I'm not here to say who knew what when," Conway said, after being repeatedly pressed on what Trump and Pence knew regarding Flynn's call to the Russian ambassador before the inauguration. "I don't know all the details."
Responding to questions about whether Flynn was kept on too long after the White House received a warning from the Justice Department about Flynn's potential vulnerability to Russian blackmail, Conway attributed his remaining on the job to Trump's sense of loyalty.
The president "is a very loyal person," Conway said.
Retired Army Lt. Gen. Keith Kellogg was named acting national security adviser to replace Flynn, who admitted in his resignation letter that he "inadvertently" gave "incomplete information" about multiple calls with the ambassador.
Flynn previously denied that he spoke with the ambassador in December about sanctions the United States imposed on Russia for its suspected interference in the 2016 presidential election — a discussion that may have violated federal law.
Pence repeated the denial when asked about the situation in January, but administration officials noted that he was relying on information provided to him by Flynn.
Sources in the administration confirmed that the Justice Department, under the direction of then-acting Attorney General Sally Yates, informed the White House in January that Flynn may have misled Pence and other senior officials about his communications with the ambassador.
Conway praised Flynn's resume and said he had an "honorable career in the military" that lasted over 30 years.
