Washington: While House Speaker Nancy Pelosi ordered a safety review for Muslim Minnesota congresswoman Ilhan Omar and her family Sunday after accusing President Donald Trump of putting her in danger by tweeting a video of her spliced with footage of the 9/11 attacks, the White House defended Trump's actions.

Trump's spokeswoman Sarah Sanders, defended the president on Sunday against accusations that he was inciting violence toward Omar. Omar has been at the centre of an escalating row after a clip emerged of her characterising the deadliest attack on US soil as "some people did something."
