A major US conservative forum has dropped Donald Trump as a speaker, saying it was unacceptable for him to suggest that a journalist was tough on him because she was menstruating.
Mr Trump said Megyn Kelly of Fox News “had blood coming out of her eyes, blood coming out of her wherever“.
Ms Kelly challenged him on remarks he made about women during a TV debate.
Red State said Mr Trump was implying she was hormonal, though Mr Trump later denied this in a tweet.
“Re Megyn Kelly quote: ‘you could see there was blood coming out of her eyes, blood coming out of her wherever’ (NOSE),” he wrote.
Mr Trump was one of 10 Republican presidential candidates in a TV debate co-hosted by Ms Kelly on Thursday, which was watched by a record 24 million people.
Early on in the debate, Ms Kelly asked him why voters should elect a man who has called women “fat pigs, dogs, slobs and disgusting animals”.
Mr Trump joked that he only said that about TV personality Rosie O’Donnell before adding: “I don’t have time for total political correctness.”
After the debate, he took to Twitter to say Ms Kelly had “really bombed” and thatshe hadn’t been “very good or professional”.
