Move comes after rightwing Republican accuses New York City mayoral candidate of concealing support for ‘terrorism’

The Trump administration has raised the possibility of stripping Zohran Mamdani, the Democratic mayoral candidate for New York City, of his US citizenship as part of a crackdown against foreign-born citizens convicted of certain offences.

Karoline Leavitt, the White House press secretary, appeared to pave the way for an investigation into Mamdani’s status after Andy Ogles, a rightwing Republican representative for Tennessee, called for his citizenship to be revoked on the grounds that he may have concealed his support for “terrorism” during the naturalization process.

Mamdani, 33, who was born in Uganda to ethnic Indian parents, became a US citizen in 2018 and has attracted widespread media attention – and controversy – over his vocal support for Palestinian rights.
