Donald Trump's newly-appointed communications director has quit after a senior staffer hinted he could be involved in a salacious sex scandal.

Jason Miller announced on Saturday he will not be taking on the role of communications director, citing the need to spend more time at home with his family.

Miller, who is expecting a child with his wife next month, was tapped by Trump to lead the White House press team on Thursday.

'After spending this week with my family, the most amount of time I have been able to spend with them since March 2015, it is clear they need to be my top priority right now and this is not the right time to start a new job as demanding as White House Communications Director,' Miller said in a statement, The Hill reports.

'My wife and I are also excited about the arrival of our second daughter in January, and I need to put them in front of my career.'

However, less than 24 hours before Miller announced his change of heart, Trump strategist and senior staffer AJ Delgado fired off a series of tweets suggesting there was more to the shock departure than the administration would admit.

'Congratulations to the baby-daddy on being named WH Comms Director!' Delgado wrote in one since-deleted tweet, Mediaite reports.

'When you try to put on a brave face and tweet about nonsense to distract, your feed looks like @Jason MillerinDC's,' she tweeted, before adding, 'When people need to resign graciously and refuse to, it's a bit… spooky.'

She went on to respond to a person by saying Miller, 'needed to resign... yesterday', before calling him the '2016 version of John Edwards.'

Edwards, a former Democratic senator, infamously had a child with his mistress.

He repeatedly denied the allegations, which surfaced in 2007, before admitting he was the child's father in January 2010.

Delgado has since deleted her Twitter account.

Miller and Delgado found themselves at the center of a controversy this year when it was revealed they had visited a Las Vegas strip club together the day before the final presidential debate.
