US REAL ESTATE developer Donald Trump is back to trashing Fox News host Megyn Kelly, the day she returned from her vacation after the Republican presidential candidate’s high-profile feud with her.

In a series of tweets, Trump blasted Kelly’s performance on her show, The Kelly File, and promoted tweets calling her a “bimbo” and comparing her looks to those of an older female TV host, Nancy Grace.

Ceasefire?

The Trump attacks are notable because he and the network had struck a public cease-fire earlier in the month.

Kelly moderated the first prime-time Republican presidential debate and asked Trump a series of questions Trump described as unfair, including one about derogatory comments he has made toward women.

The developer lashed out at Kelly after the debate and in a series of interviews blasting her, he made a particularly controversial comment that many interpreted as a sexist reference to menstruation.

“You could see there was blood coming out of her eyes, blood coming out of her — wherever,” Trump said of Kelly during the debate. (Trump later insisted he meant “nose” or “ears”; “Only a deviant would think anything else,” he added.)

Relations between Trump, who polls show is the Republican front-runner, and Fox, which has an outsize influence among GOP voters, continued to publicly deteriorate.

Kelly even reportedly received death threats from Trump’s supporters. Eventually, Fox News chief Roger Ailes and Trump had a “blunt” conversation that they said resolved their differences.

But Trump is clearly not done criticising and mocking Kelly:
