The message inside the card includes a handwritten note in broken English stating: “No Jew can be Prime Minister of England, no MP can be a Jew… We are all in a Holocaust and the white race people of USA, Russia, Europe…no shame…
“Re Trump… There’s 70 million people in our country Stella, you received 260 complaints. Get real. It’s the Jewish vote rig conspiracy. Stupid.”
After Ms Creasy, who is not Jewish, posted her tweet about the card a number of users of the social media site said they had reported the episode to the Community Security Trust.
Earlier this month Ms Creasy was targeted for abuse after voting for airstrikes against Daesh in Syria.
Anti-war activists marched on her office in east London and sent her photos of dead children.
