Didn't Flynn used to work for the Obama administration?
Yes. On April 17, 2012, President Barack Obama nominated Flynn to be the 18th director of the Defense Intelligence Agency. OnOn April 30, 2014, Flynn announced his retirement effective later that year, about a year earlier than he had been scheduled to leave his position. He was reportedly effectively forced out of the DIA after clashing with superiors over his allegedly chaotic management style and vision for the agency.
According to what Flynn had told in one final interview as DIA director, he felt like a lone voice in thinking that the United States was less safe from the threat of Islamic terrorism in 2014 than it was prior to the 9/11 attacks;
he went on to believe that he was pressed into retirement for questioning the Obama administration's public narrative that Al Qaeda was close to defeat.So....perhaps Flynn wants immunity in exchange for his testimony on Bammy??
