Donald Trump tweeted Friday afternoon that he shouldn’t be criticized for tweeting about former Miss Universe Alicia Machado’s purported “sex tape” in the wee hours of the morning because “at least you know I will be there, awake, to answer the call!”

“For those few people knocking me for tweeting at three o’clock in the morning, at least you know I will be there, awake, to answer the call!” he tweeted.

For those few people knocking me for tweeting at three o’clock in the morning, at least you know I will be there, awake, to answer the call! — Donald J. Trump (@realDonaldTrump) September 30, 2016

The comment is likely a reference to a campaign ad from Hillary Clinton during the 2008 Democratic presidential primary season, in which a narrator asked, “It’s 3 a.m. and your children are asleep. Who do you want answering the phone?”

Republicans, including Trump, have long claimed Clinton metaphorically missed that 3 a.m. call and was asleep when the attack on the American diplomatic compound began in Benghazi, Libya. But congressional inquiries have found Clinton was immediately engaged in the response to Benghazi.
