Jerry Brown has officially announced his run for re-election as governor of California.

In a statement published Thursday on his website, jerrybrown.org, the governor touted what he saw as his achievements in office over the past four years — the Dream Act, prison realignment and school funding among them.

Brown, 75, also laid out a host of challenges that he said the state still faced, including underfunded pension and retiree health care plans and an ailing infrastructure, which he said he would address if elected to a second term:

"At this stage of my life, I can say--without any hesitation--that I am prepared and excited to tackle these challenges and the many others that lay before us. In fact, there is nothing I would rather do. So today, I have taken out the papers to run for re-election."

Brown's Twitter account carried a picture of him filling out that paperwork.
