Scott Walker tweet says he’s running, but who posted it?

Twitter says it’s investigating a premature presidential announcement that popped up on Wisconsin Gov. Scott Walker‘s account Friday evening.

The message, which was quickly deleted, said, “Scott Walker is running for president.”

Twitter spokesman Nu Wexler said later, “We’re looking into today’s issue, and we’ve determined the Walker team was not at fault.”

After the initial tweet, the Walker campaign did not deny responsibility, saying only, “Stay tuned for Governor Walker’s announcement on Monday.”

Later, Walker press secretary AshLee Strong said, “We’re happy Twitter confirmed this wasn’t Team Walker’s post and are investigating what happened.”

It’s no secret that Walker will enter the 2016 Republican presidential race in Wisconsin on Monday afternoon. He is set to become the 15th Republican presidential candidate after he confirms his intentions Monday.
