On case of the AfD it is rather Mccarthy's old outfit deciding to treat his new one as a threat. The Verfassungsschutz, the German federal interior secret service, decided to watch the whole party as threat for democracy. The Verfassungsschutz was headed by a certain Mr. Maaßen who is now touting right wing conspiracies i social media. The minister responsible for the agency once prouded himself of deporting 69 Afghans on his 69s birthday. Ajd they are treating the AfD as a right wing extremist group now. Should tell you something. Or not.
