Washington: In a rare move, the US House of Representatives has passed a resolution to condemn President Donald Trump's "racist" tweets against four non-white Democratic congresswomen who have been critical of his harsh immigration policies.

The vote on Tuesday came days after Trump's tweets about four newly elected lawmakers – Alexandria Ocasio-Cortez of New York, Ilhan Omar of Minnesota, Ayanna Pressley of Massachusetts, and Rashida Tlaib of Michigan – triggered widespread uproar. In a series of controversial tweets, he had said the Congresswomen should just "go back" to where they came from.
