Donald Trump has said Democratic congresswoman Ilhan Omar’s latest controversial comments about the US-Israel relationship represent a “dark day” for the Middle East country. Ms Omar, the first Somali-American elected to Congress, has been forced to defend herself in recent days following an event last week in which she claimed she was being pressured to pledge “allegiance” to Israel. “I want to talk about the political influence in this country that says it is OK for people to push for allegiance to a foreign country,” she told an audience in Washington on Wednesday.
