Donald Trump has attacked Michigan Democratic Senate candidate Abdul El-Sayed, calling him a "communist loser" after El-Sayed secured a narrow primary victory, as Republicans reassess their strategy for holding the seat and protecting their Senate majority. The clash reflects the high stakes both parties are placing on the Michigan race, seen as a key battleground that could shape control of the chamber.

Trump's comments singled out El-Sayed's left-wing politics and the closeness of his win, suggesting Republicans believe his positions make him vulnerable in a general election. Republican strategists are reportedly weighing new approaches to capitalise on El-Sayed's narrow margin and progressive platform as they look to defend or expand their Senate majority in the upcoming election.
