OJ Simpson joins Twitter, warns he's 'getting even'

OJ Simpson has joined Twitter with a video warning he's "got a little getting even to do".

The former football star and actor was acquitted of the murders of Nicole Brown Simpson and Ron Goldman after a highly publicised trial in 1994.

He was later convicted in 2008 of armed robbery and kidnapping in a separate case, and parolled in 2017 after serving nine years.

A 2016 poll found 83 percent of white Americans and 56 percent of African-Americans think he did kill his former partner.

Simpson announced the creation of his social media account with a challenge to his critics.

"You know for years, people have been able to say whatever they want to say about me, with no accountability," he said.

"But now I get to challenge a lot of that BS and set the record straight."

Despite having posted just two tweets, Simpson has already gained over 387,000 followers. He said they'll be able to read his thoughts and opinions on "just about everything", including politics. And he finished with an ominous warning.

"This should be a lot of fun. I got a little getting even to do."
