In November 2018 it was reported that Rathbone was facing disciplinary action from the Labour Party for her comments a year earlier in which she suggested that the Jewish community's need for security at synagogues stemmed from a "siege mentality". She had said "The fact that the Jewish synagogue in Cyncoed is, is become one of these, you know, fortress is really uncomfortable." she went ond "How much of it is for real and how much of it is in their own heads is really hard for an outsider to judge, but I think siege mentalities are also part of it."
The synagogue's rabbi, Michoel Rose told BBC Wales the comments were "Extremely Offensive".
She was suspended from the Labour assembly group for six weeks, and UK Labour decided no further sanctions would be issued. She said she was "Profoundly Sorry" for the remarks and for the offence caused. A Labour disciplinary panel decided not to expel Ms Rathbone, or issue a further suspension.
The Cardiff Central AM was ordered to undergo anti-Semitism training, something she had already volunteered to do.
GBNews has been banned by the Welsh Sened on all internal TV feeds at the behest of the Anti-Semetic Corbyn supporting Labour Politician Jenny Rathbone. Turning to 'X' she proudly exclaimed she had finally got her way.
"Pleased to report that the toxic GBNews is no longer broadcast on @SeneddWales internal channels."
"No place in democratic discourse for Laurence Fox’s unbridled misogyny or echo chambers of misinformation with no fact-checking. Good journalism essential in challenging times"
When asked for a comment by a GBNews reporter she hid behind one of her assistants and claimed she was doing an interview with the BBC instead.
[ A reminder that the BBC, along with CNN, MSBNC, etc, are all members of an International News Organisation whose goal is to stifle smaller independent unaffiliated news agencies, and to ensure only their point of view is allowed. ]
Fellow Conservative members were shocked and dismayed at the decision, pointing out that in a democracy all voices should be heard and not just hers, as that would make it a Totalitarion Dictatorship. They vowed to reverse this ban.
