The Office for the Protection of the Constitution has taken a look at Maaßen. The former head of the authority he previously headed has now given him this in writing upon request.
The BfV does not comment on individuals due to the protection of personal rights. If the person concerned believes that they have come into the focus of the intelligence service, they can request information from the Federal Office as to whether their personal data has been stored. According to the letter that has now been published, Maaussen did this last August. Resigned from the CDU a few days ago.
