The Trump picture appears to be a reference to comments made by Pete Willsman, the member of Labour's governing body who ranted during one of its meetings about how British Jews were "Trump fanatics" who were making up allegations of antisemitism within Labour.
Despite widespread outrage after the JC released a recording of Mr Willsman at the meeting, the far-left member was still re-elected to Labour's National Executive Committee earlier this month.
Jackie Schneider, the Parliamentary candidate for Wimbledon Labour, told the JC: "This kind of harassment is wholly unacceptable. It is outrageous that Rebecca has been targeted in this way. I hope that whoever did this is caught. I have sent Rebecca my full support."
Dr Moses won support from prominent Labour MPs, including former leadership candidate Yvette Cooper. But she deleted her Twitter account after tweeting about the incident.
