Disappointment over Flynn's resignation, 24 days after assuming the role, was felt widely in internet discussion boards like Stormfront and The Daily Stormer, alt-right outlets. Members blamed everyone from the media, Mike Pence, the intelligence community and Jews.
Andrew Anglin, creator of the neo-Nazi news blog The Daily Stormer offered his own commentary, labeling Flynn as "one of our best guys," and describing the resignation as "definitely a loss. To the Jews." The website's readers agreed, several called Flynn "the kind of person we need on our team," "stand up," and that he was "too pro-white" for the administration.
A prominent "alt-right" news blog edited by white supremacist Richard Spencer also aired its dismay over the news, considering the resignation "a huge mistake."
