Here is the link: https://www.bild.de/politik/ausland/politik-ausland/usa-trump-anhaenger-planen-den-naechsten-sturm-74812924.bild.html

Basically what they are saying is that "Trump-extremists" already plan the next attack. And then they got a quote from someone on td.win.:

"Auf „thedonald.win“ schreibt ein Anhänger: „Patrioten, die zu diesem Zeitpunkt immer noch zu feige sind, um Gewalt zu dulden, sind Teil des Problems.“"

Translated: "Patriots, who at this point are still too cowardly to tolerate violence, are part of the problem"
