This comes after a campaign that has been going on for weeks claiming that Die Linke is antisemitic (the left-wing party that got the most votes in Berlin's most recent election). CDU (the current national governing party) has been pushing the narrative that Die Linke is comparable to AfD, because they call for human rights in Gaza and to stop the unconditional support for Israel by the German government.
the timing is fortunate then in my opinion :)
