With 354,000 followers and counting, O.J. Simpson is taking Twitter by storm — vaguely promising to “set the record straight” in a second video posted Saturday night, a day after first testing the waters with an inaugural tweet.

“Hey Twitter world,” he says in the new video, which shows him standing in front of his backyard pool. The video had been clicked on 673,000 times within an hour of going live.

“You know for years, people have been able to say whatever they want to say to me, with no accountability,” he complains, amiably, waving a pair of sunglasses around in his left hand.

“But now I get to challenge a lot of that BS and set the record straight,” he promises.

“More importantly I’ll be able to talk about everything, especially sports fantasy football. And even politics. But for now let me just say to my fellow fathers out there, happy Father’s Day . And God bless.”

Simpson, 71, caused a flurry of speculation when his first tweet surfaced Friday night — a now-viral video in which he warned with a smile, “I got a little getting even to do.”

Within 24 hours, that video had been clicked on nearly 7 million times.

He confirmed to the AP Saturday that the account was genuine, saying in a phone interview while on a Las Vegas golf course that tweeting “will be a lot of fun.”

He added, without elaborating, “I’ve got some things to straighten out.”

Simpson’s trip to Twitter, with the handle @TheRealOJ32, comes 25 years to the week after the stabbing death of Nicole Brown Simpson and Ron Goldman in Los Angeles.

Many — if not most — of his readers are eagerly trolling Simpson.

“Do you have nay new murders coming out in 2019?” asked comics artist Jon Rosenberg, @jonrosenberg.
