South Dakota Senator Tim Johnson, who had a major brain hemorrhage in 2006, Tuesday announced that he will not seek re-election in 2014, according to the Associated Press.
One of the reasons Johnson, 66, cited was his struggle to recover from the brain injuries he suffered seven years ago. In fact, he came to his press conference to announce his retirement in a motor scooter, and at times slurred when he delivered his speech.
Johnson told reporters that his right arm and right leg remained impacted by his brain injury, and that he was still having issues with his speech, AP reported.
In addition to his medical condition, Johnson said he wanted to spend more time with his five grand kids.
