Party: He was registered as a Democrat in North Carolina, where he lived for a time, and served in the Obama administration.

Key Life/Career Moments:
In 2004 to 2007, Flynn served as Director of Intelligence for the Joint Special Operations command under Gen. Stanley McChrystal, with stints in Iraq and Afghanistan where he was a key figure in dismantling insurgent networks.
In addition to Iraq and Afghanistan, he was deployed as a platoon leader in Grenada in 1983 and was Chief of Joint War Plans in Haiti in 1994.
What You Might Not Know About Him:
He resigned as the head of the Defense Intelligence Agency a year earlier than he was supposed to, according to The Washington Post.
In a 2010 blueprint, Flynn said the U.S. is too focused on insurgent groups in Iraq and Afghanistan and lacks concentration on future threats. He called for more analysts abroad to gather and streamline this information.
Flynn's final thoughts upon retirement from the DIA, as posted on Department of Defense website, were: “As you walk away from my retirement ceremony today, if you consider anything that I say, it is that we had better be prepared for and ready and willing to use every fiber of our being to maintain the kind of life that we enjoy in this country.”
In February, Flynn tweeted, “fear of Muslims is RATIONAL.”
He has consistently maintained that Hillary Clinton should recuse herself from the race for president because of questions surrounding her use of a private email server as secretary of state.
What He Has Said About Trump:
Flynn originally declined to comment in great detail about his meetings with Trump. In a Feb. 12 interview on CNN, he said Trump was one candidate he had advised, but that he is “advising any candidate that has asked me for advice on a range of issues, national security, foreign policy.” He told The Daily Beast via text message in January that he and Trump had “met informally,” but did not expound on this and also did not respond to Reuters’ request for comment for a March article.
In May, he did not condemn Trump’s proposal to ban all Muslims from entering the United States, but said he was working with Trump to be more conscious of his remarks: "There must be more precision in the use of the language that he uses as the potential leader of the free world," he told Al Jazeera English’s Mehdi Hasan. “There has to be more precision and those are the types of advice I am trying to get into him. Be more conscious about what you say about foreign policy issues because they are complicated.”
