UPDATE (6/15/15, 9:11 p.m. ET): Although Killer Mike wanted to run as a state representative in Atlanta, it appears he won't be able to just yet. The rapper took to Instagram once more to announce the news.

"I can't run," he said. "But for the folks that were willing to write in #MichaelRender, thank you so much. I am gonna run one day and we will win. However, in Georgia, I would have to officially enter as a 'write in' versus being an actual write-in (those are the breaks) but, I really felt it important to draw attention to this race."

Earlier today, Mike said the following:

"In Atlanta, Georgia, there will be special election tomorrow for District 55," Mike said. "Former state representative Tyrone Brooks no longer sits in the seat. I would like as many people as possible to go to the polls and write in Michael Render. Why? Because if I win, we win. Thank you. Now go vote."

Brooks announced his resignation in April just before pleading guilty to federal tax, mail and wire fraud, as per Atlanta Journal Constitution. He also said he wanted to "transition back to full-time Civil Human Rights work," in a farewell letter, according to a separate AJC story.

This year, the public has heard Mike address several social issues publicly. In August, he spoke about Michael Brown and Ferguson with CNN. In May, Mike discussed Freddie Gray and the Baltimore unrest. Throughout the year, he's been critical of law enforcement with songs like "Early" and he's celebrated the good work done by police, too.

Mike - who attended this year's White House Correspondents Dinner - may expand on his aspirations today when he appears on "The Nightly Show With Larry Wilmore."
